In the four issue mini series "JokerMask" (Darkhorse-DC crossover) there is
a picture of Max on the first issue. Go to the second page and the first
panel there (it takes up the top half of the page) and see The Joker and
Harlequin walking though the museum. Now examine the glass display case full
of masks on the right. You will see that on of the masks is Max's head.

I tried to e-mail a couple of guys who would post it on their site, but it kept getting sent back to me because of delivery problems. I didn't know who else to tell, so I decided to just post it here.
