In recent months, I've had a chance to watch a bunch of DVDs of 1970s TV shows, which are really, really expensive to buy, but fortunately also available to rent at some local shops. There are also quite a few movies out there, mostly related to the big properties like Godzilla, Ultraman, Kamen Rider, etc.
Along with the shows, there's a very rich selection of print based material, going back many decades. You've got manga, photo books, pop up books, bromide cards, stickers, and much more. A lot of it is amazing stuff. Then there are posters, which seem to have a loyal fan base as well. Here's a look at some, along with some paperwork from anime, kaiju, and tokusatsu lines:

|Thunder Vs. Gaira|
