(original Dutch: citaat van Willem Roelofs, in het Nederlands:) Ik heb het eenige nog niet verkochte schilderij dat voorl. jaar te Rotterdam was, overgeschilderd.. .Mij dunkt, dat het er nog al aangenaam en goed uitziet.. .Ik wilde dat gij hem zevenhonderd guldens voor vroeg.. ..voor zeshonderd zou ik het uiterlijk kunnen laten en meent gij, hem kennende, het beter zou zijn dadelijk die prijs te vragen zoo doe het dan.

I was sorry for Gabriel that all the efforts you have employed so diligently were in vain to help him to sell one of his paintings in [the exposition in Amsterdam, in] 'Arti'. Is there not any chance to order from him a small presentable painting (backed up by me, if it will help) for one or the other? He really deserves it and hundred guilders can mean so much at some moments. (translation from original Dutch: Fons Heijnsbroek)

Dear Lords, I hereby have the Honor to announce You that the painting 'Het Binnen komen der Haringschuiten in Scheveningen' has been sent today to your address, for your upcoming Exhibition [in Arti, Amsterdam]. The price is f 2500-. I also declare to stay out of competition for the medal. Yours sincerely HW Mesdag. (translation from original Dutch: Fons Heijnsbroek)

Dear Sir Verloren. Today I send you a drawing for your art-reviews. I would liked to have done more for you, but I have many demands for drawings from all sides and I am still very busy with paintings after my studies I made during the last trip. I hope that the drawing will be acceptable. The price is 150 guilders. I am not sure you need a title, call it just simply, 'Bij een Drentsch dorp' (At a village in Drenthe). (translation from original Dutch: Fons Heijnsbroek)

My [dear] Sir: Let me first offer my kind regards. I agree that I should come soon to see how the picture accords with the rest. As regards the price, I certainly deserve 200 pounds for it, but shall be content with whatever His Excellency pays me. And if you, Sir, do not deem it presumptuous, I shall not neglect to requite the favor. Your humble and devoted servant Rembrandt - It [the picture] will show to [the] best advantage in His Excellency's gallery, since there it will be [displayed] in bright light.

I also sold some drawings [he means his watercolors] - the Dutch pieces [he painted in The Netherlands] sell rather well [in Brussels, where he lived then]. People seem to prefer colored drawings here. (translation from original Dutch: Fons Heijnsbroek)

I have an idea - that still-life with the two bouquets I still have here.. .It will fit in your home perfectly - and I would really like to see it hanging there myself.. .You don't have to pay it at once if that doesn't suit you now. Then pay me in 2 times 100 for example,. in the beginning of next year?. .You will be happy with it - ànd - the painting is in the right place.. (translation from original Dutch: Fons Heijnsbroek)

Last Saturday it was a rainy evening. I took advantage of that to draw once again the whole evening at Dam Square all over and Sunday I repainted my painting [of Dam square] completely, that yellow nasty color has disappeared now completely. The work has become much broader, and I believe it is really finished now. When my model came, the change struck her so strongly that she said, 'sir, the painting has become beautifully now'. I myself am very happy with it, because I believe it is really good. (translation from the original Dutch, Fons Heijnsbroek)

[one watercolor] is in spite of all its difficulties, and perhaps because she has given so much trouble, less fresh and has become a little heavy - I myself have considered for a long time whether she was good enough to send it [for a exhibition in Utrecht] (translation from original Dutch: Fons Heijnsbroek)

I take advantage of a painting that I now have at the Paris' exhibition. 3 orphan girls who are sewing in an interior room. I have sold [it] there for a nice price and have heard some interesting reviews published about it. (translation from the original Dutch: Fons Heijnsbroek)

In the afternoon he [ Johannes Bosboom ] took me to look for it [her first showed painting, ever]. There it was! I thought I was swimming! And next day, our lounge was full of people [at home, with her father], a friend of dad came in and he said: 'I have seen your painting. Very well, indeed. Do you know it just has been sold?' Suddenly it fell silent in the room. Daddy looked at me with surprised eyes. It was my declaration of independence. (translation from the original Dutch: Fons Heijnsbroek)

A painting is finished when one can see what it represents. (translation from original Dutch, Fons Heijnsbroek, 2018)

Snow had fallen and from the museum [in Pittsburgh, The ] you had a beautiful view of a valley with a railway, through some sheds, etc. But I could not finish it, and today, Sunday, I went back there again, but then the snow was already so far away that I could not make anything of it any more. It is a pity. Otherwise I could have sold something. [The painting was sold to the Stedelijk Museum Amsterdam in 1934] (translation from the original Dutch, Fons Heijnsbroek)

..I would like to ask your advice as a friend, namely whether you believe I should submit my painting 'Ouden en Jongen' [Old and Young ones'] to Brussels [exhibition] or not. I thought it was a nice painting, but now I read in the Handelsblad that it is so bad. What is truth about that. Please do me the favor to sent me some words sans facon [straight forward], what is your opinion about this. (translation from the original Dutch: Fons Heijnsbroek)
