I used Bob Marshall's list of Ticklers from that I first contacted Max Speer and a conversation was started about a possible meeting in Philly with other people he knew that are into tickling
Do I remember Tobias Hackner ! I still remember his catch phrase " Ticklers Of The World Unite"!
I order my very first tickling material from him in the mid 80's from his advertisement on the back of FETISH TIMES magazine. He could have been a crook and take my money but he didn't! Between him...
