Hey, take a look at this page by Erik Larsen page from SAVAGE DRAGON #41 , a big wedding issue where a lot of characters from various creator-owned books show up (like the DNAgents, E-Man, Flaming Carrot and Zot), and of course where villains crash the party. Can you spot Mr. Spook?
Took me a while, too. Here’s a close-up, along with Ted the Bug from Jeff Smith’s BONE.
The cameo probably appears in the various collected reprints that include this issue.
