Batman #243 and #244—August and September 1972.
Molly as a character seems not to have been forgotten. In the August and September 1972 issues of the Batman comic, a character named Molly Post surfaces. The similarities are definitely there:
Red hair? Check!
Gorgeous figure? Check!
A skiier, just like Jill St. John was in real life? Check!
Granted, this story was set in Switzerland, not Colorado, but so it goes. We definitely need to talk with Neil Adams about this!!!
