It looks to be done on vellum but I'm not sure. My wife bought an old frame at a local Goodwill for a project she was working on and this was hidden inside. I'm sure it's worth more than the 99¢ she paid for it but don't know if it's worth having it framed again. If anyone can help, it would be appreciated.
I know this is COMPLETELY Non-Casino Related but so many of us have other hobbies and interests it only made sense for me to ask here first. I hope no one minds.
