1962 Topps Mars Attacks Non-Sport Forum

There are two checklists on the site for the Mars Attacks set. One for Bubbles Inc and one for Topps.  All the cards in the (supposedly) Topps set have a Bubbles Inc copyright.  As a matter of fact, I have never seen a card with a Topps or TCG copyright. Are Bubbles and Topps, in this case,  the same?  Is there a need for two checklists?  Any ideas?

From this, Bubble Inc was what Topps used for this set. Looking at the Change Log looks like the person who entered the Bubble Inc set just saw that on the copyright line and entered it as a new set.

"With global tensions rising during the Cold War, Topps (under the name Bubbles Inc.)..."

Good stuff. Thanks. I guess there is no need for a Bubbles Inc. checklist.
