Here's the splash page from the digest reprinting of Mento's first appearance.
Conveniently enough, the issue this is a reprinting of is also the first appearance of Garguax in Doom Patrol (first volume) #91.
I figured this was a great choice for Negative Monday, as Larry and Mento are both struggling for Rita's attention. I'll be posting more about this issue and these characters in the next few days this week. Heck, maybe I'll try something new and make this week all about one issue.
Tune in and find out.
