Adam Brick Guy is not associated with, endorsed by or even second cousin related (as far as we know) to anybody with those major brand names of bricks. They are great bricks & brickmakers and we don’t want to meet their lawyers. We are just a bunch of silly people doing a bunch of good in the world, so we play nice and we know that everybody retains their respective copyright, trademark and other legal monikers with their bricks. We are here to build up some cool projects and have fun with kids. That's it! Thanks!
