This is an amazing shop, next to the flower market, and full of incredible prints, both originals and reproductions. We bought several of both categories and the owner was very friendly and helpful. It is easy to find, located next to the flower market on Single, off of tram line 4 and 12. We were there in December 2018 and made a special trip back again when visiting in May 2019. It will be on our itinerary for every visit we make to Amsterdam!
