I actually just bought them. Only flipped through Vol. 1 so far. Didn't see supplements. Not oversized. It's actually made with the same 80s newsprint paper that my old trade and the original issues were made with. At first I was upset, but now I actually find it kind of endearing in a nostalgic way. But likely a turn-off for most people. If you already have the trades, you're only upgrading the cover.
