Joseph Tomanek and Archibald Motley
According to a wall display at the current Archibald Motley exhibit at the Chicago Cultural Center, the above photo documents a model that Motley shared with Palette and Chisel member, Joseph Tomanek, in his studio in Berwyn.
And this photograph may have been taken in Tomanek's studio in 1921.
Motley is holding the umbrella in back -- and I suspect that Tomanek is holding the violin at the far left ( he was a prize-winning fiddler)
These pictures were taken soon after both were fellow students at the Art Institute.
Motley would go on to earn a reputation for his scenes of jazz clubs - while Tomanek would paint murals for churches and pin-up girls in the great outdoors.
