We've gone ahead and added one of our favorite items to eBay - the On Air sign from RCA Radio Station in Washington, DC. The light is from the 1930's and is in amazing shape for its age. Super rare to find one in this condition. Bidding starts at $400 and has no reserve. Link is below. Good Luck bidding!
Thanks to everyone who bid! The light ended up with 20 bids, 42 watchers and over 460 views! Thanks to all.
