Wow anything Tricorn related is great (its how I stumbled upon this site) and any new pictures are great, most websites seem to have the same 5 views and thats all.
I'd love to see any more pictures you have, plus do you have a copy of that original flyer or is it a scan you found somewhere? I have been looking for original material for some time, and apart from a few bits a pieces in Portsmouth Library nothing much has turned up. You'd think a building like the Tricorn would have more written about it.
