Rainbow Brite Lamp

I have had this lamp for at least seven years when I happened to pick it up during a particularly childhood-nostalgia-fueled trip to the local thrift. It had a yellow light bulb, but no shade. I never plugged it in due to this lack of shade, and after never having bought a shade, I generally have no fucking clue as to why I still have it. ebay, I guess? It's probably the reason for a lot of "Maybe someday I'll make money off this...?" internalized hanging questions.
