Mildly uncomfortable experience visiting Harper's Books... a common problem within the art world is often the staff act superior (not knowing who you are, or what gallery you are with). The staff were somewhat passive and pretty much talked me out of buying in their store, unaware I was prepared to acquire a lot of titles. The "rare" books on sale can mutually be found on eBay or AbeBooks for half the price. An artist(s) objective is one of inclusivity but some continue to push elitism.
