Mary Marvel is quickly gaining on Power Girl for the title of most commissioned character.
This commission is the first of two Mary Marvel commissions I've been working on this week. But they're for different buyers, incidentally. This one was an homage to an old cover from the 40s (maybe early 50s).
I'm not sure which issue the character first appeared in, but the comic this cover is based on is called "WOW".
I'll be finished with Mary Marvel #2 tomorrow or the next day.
