Wanted: Muppet Style Guides

[zombiepencil]

I don't know if this is the correct spot to ask about this, its more a collectible I guess.

I only recently learned of these Muppet Style guides for sesame street and the muppet show. I assume that these are typically acquired from those working with the muppets, but I see that a few people seem to have them.

While I would love to own actual copies for my personal collection of concept books, I was wondering if anyone might know where scans of the books might exist? Or if an own would be interested in helping an image reference collector feed his image files
