Ron,

 

Is there paint on the signs, below the cellophane?  If there is, this makes
the situation tricky.  

 

Do you know what kind of plastic the signs are made of?  1960's plastic
could be of any number of types that have varying properties. 

 

Not knowing what we're looking at I'd be remiss to suggest something.   If
the base plastic is resistant to heat I'd recommend getting a steam cleaner
(cheap one) to apply some heat to the cellophane without changing the
structure of the sign.

Subject: removal of cellophane from plastic

 

A patron of ours queried us to the proper way (if there is one) to remove
cellophane that has adhered to molded plastic. The items in question are
molded plastic trade signs from the early 1960s. I am hesitant to recommend
an acetone based product. Any ideas?
