Greetings -
Last year, Paul Doherty and I cobbled together a 'MARK shirt', which we (and several others) wore at a MARK workshop to honor Gary who was (at the time) verging on retirement. Since then, and most recently at the just-finished workshop last week, we've had a number of requests for such things (i.e., folks have asked where they could get a shirt).
I've created an online 'store' for such things - including a MARK mug for you coffee/tea drinkers. Simply point your browser at

The prices contains absolutely no markup (i.e., no profit) - they reflect production costs. The shirts have the MARK logo on the front, plus RTFM on the back (a sure-fire conversation starter if you wear the shirt out in public...).
I've generated a selection of different shirt 'types' - hopefully, those of you wanting to make such a sartorial statement will find something you like.
