This is an old Olympia Beer Lighted Sign with a wood frame. Measures 12 1/2" by 8 1/2" by 2 1/2" and was made by Brightco Electronics of Westminster, California. Paper label on the back states that unit uses any C7 1/2 watt Christmas twinkle bulb or model No. S 7 1/2 Brightco Flasher Bulbs and if it lights but doesn't twinkle the bulb needs replaced and the unit is not defective. It does light up and looks great but so far haven't seen a twinkle, so if you want a twinkle, assume the bulbs need replaced. It also has a dimmer switch on it. Sign has great color and in good condition and would make a nice addition to your collection. Buyer to pay shipping in USA. Thanks for looking.
