Philip Williams Posters is a wonderful warehouse of both original vintage posters and budget friendly midsize posters. Most posters cost around $15-20, but you can buy postcards for $1 each and card stacks for $5! The original vintage posters are more costly, but due to its authenticity I think it is worth the price! I bought 10 postcards ranging from retro movie posters to various covers of The New Yorker. Super fun way to past time in NY without breaking the bank!
