Its all books mostly. Of course theres the concept art booklet I got from eBay (seen underneath the Pluto figure, the Omega Factor game and the Tenma statue), but theres also a more recent book that showed up. The little grayscale one in the corner to be specific. Its a compilation of multiple storyboards used for the 1960s and 80s TV series. It also happens to share some of the drawings shown in the concept art booklet I got from eBay, this book however was put out sometime in the 90s and is an actual published work while the other was made (presumably) for the animators of the original show.
