Deathstroke / Yogi Bear Variants

When the Deathstroke / Yogi Bear special was announced, the cover below was displayed as the main cover.

Recently, this second cover was revealed as a variant.

But Forbidden Planet, which calls itself the "the largest UK stockist of the latest comics and graphic novels" displays a different cover.

They make no reference to the above cover being another variant. They seem to list it as the regular cover. Perhaps a different cover is being used for the European market? In any event, I found it difficult to come by and therefore thought it might be worth sharing.
