Wow, nice catch. I've updated it.

If you're referring to the Christmas Catalogs & Holiday Wishbooks site, none of the search results for "Odyssey" are relevant in that time frame, and I didn't see it browsing through. And yeah, it looks like you're right about them not being sold widely initially.

I put together a collection of every catalog and circular ad I could find that features video games, but I really wish I could find more for some of gaming's earliest systems. My earliest finds are from 1975, a few years after the Odyssey was released, so there must be some more ads for it out there, and others like the Coleco Telstar and Atari 2600. Does anyone here have know of some sources that I haven't come across yet, or own some old catalogs they would like to take pictures of or scan?
