Just out of curiosity, I checked out Decals Unlimited:
  http://www.decalsunlimited.com/ 

They do have a lot of replacements as Gordon mentioned, but I saw
they didn't have anything that covered the Pianola spectrum, at least
in Weber.  So be careful before you wipe that original label off
hoping to replace it with an exact reproduction of what was there.

Has anyone tried scanning/photographing their decal and having it
recreated?  That might be interesting.

I was interested to see they had T-shirts and thought it would be
cool to get a Pianola T-shirt, thinking maybe they were drawing from
their library of decals.  Alas, not an option.  Maybe I can suggest
it to their new products department.
