I repainted the only unsold picture that was [exhibited] in Rotterdam last year. It seems to me that it looks quite pleasing and good now.. .I want you to ask him [the client] seven hundred guilders.. ..for six hundred as lowest price I would be willing to sell it and if you think - knowing him - it would be better to ask that price at once, so do it. (translation from original Dutch: Fons Heijnsbroek)
