Up for bid on eBay is this Grand Funk Railroad patch.
The seller says the patch was "given to me in early 1970s by Capitol representative when I was writing for Billboard in Los Angeles."
As Simpson fans will recall, Grand Funk Railroad is Homer's favorite band. Homer once described what made this band so great: "the wild, shirtless lyrics of Mark Farner; the bone-crushing bass of Mel Schacher; the competent drum work of Don Brewer."
