Tall Wooden Arm and Hand (Mold?) wooden foot I know that reverse glass

I know that reverse glass painting was taught to young women in the first half of the 19th century and then became widely popular as a decorative art from about 1850 to 1890

Based in Girard

of which this one is emblematic

The frame is in good condition

Tall Wooden Arm and Hand (Mold?) wooden foot I know that reverse glassI'm guessing this was probably made as a mold, but I'm not completely sure. While fairly crudely done, I like it as a gesture of a raised hand, as if saying "I know the answer" and forever waiting to be called upon! 17 1 4" t x 6 1 2" w x 3 1 8" d (at base). Very good condition, pine I believe, with some darkening to the wood near the end of the arm.
