From: Paul Gachet sr.
To: Vincent van Gogh
Date: Auvers-sur-Oise, probably June-July 1890
Amsterdam, Van Gogh Museum, inv. no. b3264 V/1966
It is impossible to assign this scribbled note a precise date. Its amicable tone suggests that Gachet wrote it when Van Gogh had been in Auvers for a while, i.e. some time in June or July 1890, on a Monday.
