Whenever a marble didn't go perfectly as planned the Walds would sign those marbles Baddog. It always cracked me up back in the early 2000's when they were selling on eBay because they'd include a picture of their dog with the listing, the original Bad Dog apparently, ha ha. Strangely, these marbles somehow endeared themselves to me more because of this very fact and I have a bunch of them in my collection. I haven't sold too many of these, but here's a nice one in their Munchkin Sock style, and I'm assuming it's a Baddog because the terminations at the poles weren't quite as clean as they wanted them to be. Most likely made in the later 90's, really a sweet piece of marble history! Signed 'Baddog'.
