1950's Whistle Advertising Pam Clock. All original. The 2 coverplates are in place on the back.  The hands are original.  The face is in excellent condition.  I did not see any scratches on the glass.  There is a little raised tab on each coverplate that allows you to move the coverplate so you can access the bulbs.  One little tab on one of the coverplates is missing. It is a PAM clock. $550.00
