Willow Grove ..... Who needed a National?
The best part ... if it was possible to top that show ... was what happened after the show.
I can recall a show that Bill Mastro was not set up in the show, but he did have a briefcase with him.
He walked around that show, and handed out to people he knew, a baseball like size & shape business card ... with his name and hotel room number.

At one of those gathering's, I picked up a brown T206 Lenox.
Till this day, I don't know which was better ... the show, or the gathering?
I still have a couple of those baseball shaped business cards, and that brown T206 Lenox.
Have luck at the Philly show.
