You are bidding on a poster that shows the history of the telephone. It was produced by Western Electric, the supply unit of the Bell System. The poster shows the Evolution of the telephone from 1876 to approximately 1965. They have on phone after the 1965 rotary dial Trimline phone, which is a Picturephone. I would guess the poster dates from 1965 to 1967 or so. It is used. It measures 19 and 3/4 inches by 23 and 3/4 inches. It has some small tears and two of the corners are torn off. It is in good condition. It will be sent rolled in a hard tube or triangular box.  I combine shipping on multiple purchases.
