Yeah, Really!

Glad you noticed. I've has this one hanging around my pix collection for somoe time now:

Superman was Kinky! No, really!

I'd HIGHLY recommend this book. Millions of kinky people had their first exposure to BDSM imagery by their reading 1930s and 1940s comic books and strips. Damsels in distress, bondage, whips...Mmmmmm. Joe Shuster the co-developer of Superman, did a LOT of OTHER art too....much of it will surprise you.
