...And I didn't even know about the first one.
As best as I can tell, Excalibur Comics, in conjunction with the Wonder Woman Museum (and mannequin project?) has this going for only the second time ever this year. They're doing this during Domestic Violence Awareness time to raise awareness and also cash money for shelters and hotlines. Taking place on Sunday the 28th in Portland, Oregon and also this year in New Jersey, they have a silent auction for comic artwork and last year they got fifteen grand out of doing this. They also do tabling and fun costume stuff.
Seems like something you - and I - should support. So go read about it, buy something if you're well-heeled enough, and give a big shout out for Wonder Woman vs. Domestic Violence. With the help of lots of real people.
