In the past few weeks, I've seen several people mention the 50 Years of Helvetica exhibit at the MoMA along with some variation of "Woo! I might need to take a trip to New York to go see this!" You should know that this exhibit takes up just a small corner of the Architecture and Design Gallery on the 3rd floor...it's essentially a case and a handful of posters and other specimens. If you're in the museum already, definitely check it out, but you'll be disappointed if you make a special expensive trip just to see the Helvetica stuff.
