The Marvel HQ Tour
Marvel's world headquarters (HQ) are located at 387 South Park Ave. in Manhattan. There are weekly tours conducted of HQ, and pretty much the "waiting list" is anywhere from 18-24 months. But, yours truly (who is extremely adept at schmoozing and high quality 20s-something charm and wit), was able to facilitate a "leech" into a tour in May 2000.
Start the tour already! (coming soon)
