I told him about Collectormania LONDON in November and he definitely was interested. He enjoys coming over to England to do these kind of shows and Showmaster's is the best place for him. This is what he told me yesterday:
So please SM get Cliff Simon for any event, but particularly Collectormania LONDON.
I would be in your debt forever. Afterall, how can it be that i'm running his Official Forum yet never met him!
