Robert Frew is one of the«old-timers» in the London rare book/map trade. His shop has a very nice eclectic selection of very fairly-priced maps and prints. The book section has become a bit attenuated but still has a very good selection of general antiquarian books and is well worth browsing. Frew himself is very knowledgeable and helpful, as is the staff. It is very nice that a classic old bookshop such as this still exists and is worth visiting, especially if you’re in the Science Museum area of London.
