You never know what you're going to find on eBay. In fact, if you search long enough you'll no doubt see something weird.
The lamp in this post is a good example. Featured is a circa 1982 working lamp made especially for the band Fleetwood Mac. It features a penguin dressed up in Dodger Blue, and it has been signed on the lampshade by the Penguin himself, Ron Cey. (eBay Auction Link)
As you may know, Fleetwood Mac's mascot is a penguin. In fact, their seventh album (released in 1973) is called Penguin. Additionally, Ron Cey's nickname is that as well, so a friendship between the two seems to be a natural fit.
