I saw the larger of these at a recent Vintage show here in Portland OR. The seller said the artist was from Seattle WA, that the larger one had been exhibited, that they didn't know the artist's name, and that I could only buy it if I also took the smaller one too. Well, ok! ($20) I struggle to find a clear 'match' of the style and the name Sally, so here I am again asking for your help. Images measure 10.5"x17" (27x43cm) and 5.5"x9" (14x23cm) respectively. Thank you!
Strong vision,execution seems a tad shaky. It looks like the artist painted the signature twice -in charcoal and then maybe paint (acrylic ?).
Might very well be. Thanks for the idea. The works might be done those acrylic crayons. The under-signature looks to me to be pencil, perhaps as initially sketched, then covered with crayon.
