DC Super Friends: Heroes Vs. Villains is a "chapter book"--one of those square books you see on spinner racks in the kids department of book stores (back when those existed). It's remarkable to consider that the DCSF action figure line stopped several years ago, but it continues on quite healthily in print!
I really appreciate Russell's efforts in sending in this stuff; you can't find these books online anywhere, so they have to be physically scanned in, page by page, and I'm way too lazy to do that. But thanks to Russell the Shrine still gets to cover these in full. Thanks again Russell!
