Welcome to Muppet Wiki!
Yeah, I know they're not great, but it would be a placeholder until we find more. I'm surprised we're still finding FP records in the package!
I've just discovered that eBay searches can bring up sold and unsold completed items, and I think I ran into a treasure trove of the book and record sets which will finally make sense of all of the cover variations once and for all. Do you mind helping me with that once I figure out what I need? I don't mean to throw a bunch of stuff at you at once, but I want to link it before I forget it. I also discovered that the listings stay up for 3 months if you have the whole URL (instead of using the item number), so there's no hurry. Thanks for Geefling and Gonking!
