I was totally into Choose Your Own Adventure books growing up. I remember begging for these Darth Vader helmet bookends from the book fair at school growing up to hold my adventure book collection. Sadly, when the Vader bookends came in, they sucked and fell down if you put more than a couple books between them.
I don’t think you will have that problem with these awesome Build on Brick Bookends, since they have metal that goes under the books for stability. You can build whatever you want on these baseplate bookends using LEGO, PixelBlocks, MegaBlocks, KRE-O, and K’Nex Bricks.
You can get your set for $19.99(USD) at ThinkGeek.
