I've managed to put up some comparison shots of the Talisman base game and expansions that have been reprinted by Games Workshop on the site for those that might be interested.

Part One - Talisman, Blood Moon & Harbinger - http://www.talismanisland.com/?page_id=8435

Part Two - Reaper, Dragon, City & Woodland - http://www.talismanisland.com/?page_id=8496

Enjoy!
