Aspen Comics, the people who have been doing Fathom and other comics over the past 10 years plus, have a new thing called the "Aspen You-niverse Bundles." I think they sell for $39.99 at shows, and are later available directly from Aspen.

These contain exclusive variant covers on their comics, stickers, trade paperbacks, and other Aspen items.

Each one also has an exclusive trading card. I have seen 2 so far-- Fathom card # 1 in the first bundle, and now card # 2 of Grace in the second bundle

Each bundle is limited to 200.
