Mmuseumm

It's simply pronounced "museum" and it specializes in "object journalism" - which is a new way of collecting items that aren't rare or unusual in themselves but instead tell a story. Taking up an area roughly the size of a rental storage space (it used to be an elevator shaft) the walls are neatly lined with shelves on which items are sparsely displayed. While the exhibit is small it is routinely changed. Established in 2012 Mmuseumm was sponsored by Kate Spade - apparently one of her many generous donations during her lifetime.
