Was a London based Trad-Agency for years, very old and exclusive, only RM shots and exclusivity. A small part of travels are represented on Alamy. All these old Trad agencies like, Telegraph, Harding, Ace, Pictor, Superstock, Bagge, Zefa, CL-International, etc, etc, are all from the same time as their mentors, Stones and Image-Bank.
Some might still be around but hard to find, some of them will only contract you if youre a big name, etc.
