The Nintendo World Store was known to have many shirts available for purchase. Nintendo NY seems to continue that tradition. Some of these products were available during the Nintendo World days, but some are brand new for the store. It would also seem like many of the Nintendo NY branded clothes have a jumping Mario present on the upper right shoulder.

Also found on this page are pictures of the two coins that people could get when they purchased a Nintendo NY Grand Opening shirt with either Mario or Link on it. While these aren't shirts, I figured they should stay on the page with those items since they are part of the set.
