Here are some more six-string horrors that I found on eBay (where else?). Firstly let me present for your amusement and disbelief the Double Dragon Guitar. Or, as I prefer to call it, the Squashed Frog.
Coming from the "What letters of the alphabet haven't we tried yet?" school of design, let me unveil the Flying K.
And finally here's a cute one for the kiddies, the Lil' Kitty. At least, I think it's supposed to be a cat, although it's not a very good likeness. It looks like a rejected Daisy Rock design. (Apologies to Daisy Rock).
