Music Keyboard Patent Canvas Print – Vintage Electric Instrument Art

This music keyboard patent canvas print reproduces a 1941 patent drawing of an electric keyboard built to mount on a piano, printed on gallery-wrapped canvas in two sizes. The sheet’s cross-section figure shows the key springs and switch mechanism beneath, the kind of engineering detail a keyboardist or patent collector appreciates on sight. Made in the USA in our family shop, and hung with hardware that holds securely without nails or tools and removes cleanly without holes or wall damage.
