I found this old Whistle soda sign in the attic of a old house that was getting ready to be torn down for condo development here in Illinois,the owner of the property said there was nothing left in the house that he wanted,it was laying on the floor of the attic face down and had been cover with a thin layer of silver paint,I used thinner and a rag to clean it up.It measures 54" x 18" ,I've had no luck on finding anything out about it or any thing to compare it to in the research I've done.If anyone has any idea of its age or value,I'd appreciate any input. Thanks rvrpilot
