Not if they are ones that you know you will never have the pleasure of owning.
I'm kidding, yes always great to see the old Playboys. They were the first ones I got when I was at the Connoisseur (well, 10 each of 2 different coloured triclub chips). All gone to good homes now.
My Playboy collection has shrunk over the years (along with other things too, I suppose) but at least I know that almost all of them went to good homes which is part of the pleasure for me.
I'd start a Playboy thread so Richard and Torrey (plus a couple of others) could probably show all the ones known but I'd dribble.
Maybe a London thread soon.
