I would like to locate a colored picture of the piano used in the
movie "Casablanca" with Humphrey Bogart & Ingrid Bergman.  It can
either be a link or website online, where I can print out a copy, or a
store with an address or phone# where I can order it.

Not sure they will have it, but first place I always check for old
movie photos is LARRY EDMUNDS shop in LA.  323 463-3273.  They will do
a search over the phone for you and photos cost about $5.00.

Good morning,

there is several photos of the Piano in this website 

http://www.casalinx.com

three of them (maybe more) are colored posters. I don't know if it is
what you are looking for, but if you don't already know this website,
I suggest you contact the owners ( info@casalinx.com  ) they could
help you. There is also a  forum for the fans of the movie in this
website.
