This waving Keyboard was hand drawn with Sharpie on an early 1900's Piano Scroll. 
 
A twine string is threaded through the scroll, and tied at the top to create a loop to hang it from. 
 
Approximately, 12" x 40"long
 
**Due to having to reinforce the fragile paper by taping the back, lines appear once the scroll is rolled up and packed away. Please know that you will need to clip on weight, at the bottom, after unrolling, to smooth out the paper again. I will say that it took me 2 days with 4 bag clips to get it back to smooth, but weight and time will make that vary.
