Hulk 181 Commissions

Here are a few artist commissions for The Incredible Hulk #181, starting with Art Adams:

This commission by John Byrne also has a color version:

Here's a fairly straightforward reproduction of the original by Herb Trimpe:

And finally, this sketch cover for Wolverine #1 features Herb Trimpe doing a homage to Incredible Hulk #181 and #340 at the same time!

The Incredible Homage

Here's a few covers that pay homage to The Incredible Hulk #181.  The Incredible Hulk and Wolverine features a John Byrne wraparound cover.

I'm not sure if this cover to Wolverine battles The Incredible Hulk is by Herb Trimpe, if anyone knows for sure feel free to comment below.

Old Man Logan chapter one, printed in Wolverine 66, featured this Dynamic Forces variant by Herb Trimpe.

Here's a better version of that art, printed in Giant-Size Old Man Logan.

Wrapping things up, we have the cover to Wild Thing #0, from Marvel's short-lived MC2 line.  The title, written by Tom DeFalco with art by Ron Frenz, was the story of Wolverine's daughter in an alternate universe.
