Always liked Comic Showcase. I would go down to London on a school genealogy excursion to the public records office, located nearby at the end of Aldwych, and get bored senseless there in about 15 minutes. I'd ask the supervisor, my history teacher, if I could go off around London for a bit, surprisingly experiencing no resistance whatsoever, not even once, just a 'Make sure you're at Euston Station for 5pm'. Fair enough. (thumbs u Then it would be that tiny, original Showcase shop for a couple of hours and the original FP for the rest of the day, back when it was really excellent.
Three such highly educational and productive trips to our capital city, in total. Always returned with a bag full of advance import comics, anyway.
