If you read Games workshop's White Dwarf magazine back in the 80's then you'll know of Derek the Troll. Great fun little comic strip that I always enjoyed... I picked up a sculpt some years back (by George Fairlamb) but only for my own enjoyment. As Lew said back in 2013;

Back in 2017 Lew was doing some signings and a friend (thanks Geoff!) wangled me an illustration for the blog which I mislaid until just now!
He recently compiled all the old White Dwarf cartoon strips...
