Where in NYC? (Subway Series, No. 3)

We are back with two friezes located in a station outside of Manhattan.

Can you guess the station and subway line?

Update, 5/29/2011: These friezes were photographed at the Grand Army Plaza 2/3 Station.  The artwork is titled "Wings for the IRT, The Irresistible Romance of Travel" by artist Jane Greengold (1993) (info via NYCSubway.org).  Stay tuned for Subway Series No. 4.
