I found some paintings by Frank Walter (1926-2009)…
…18 small ones, to be exact.
The pictures were all signed on 2 February 1991. As he also designed frames, these are certainly also by him, here they are simply two glass plates glued together, with a back panel for hanging.
Frank Walter’s full name was Francis Archibald Wentworth Walter, as can be seen from the signature on the back. He lived in Antigua and was one of the better known artists in the Caribbean.
He only became known in this hemisphere in recent years, and his biography is also interesting: originally an agronomist, he lived in Europe for almost a decade, was politically active after his return in 1961 and then worked as a photographer. Perhaps this is why the pictures above have the character of Polaroid images. There are also pictures of him in his shop (e.g. here at ArtForum), on the walls of which you can see many pictures in the form above in the Petersburg hanging.
His descendants run a homepage, which provides information about research into his work and estate, exhibitions and publications. There is also an Instagram account.
