Sightseeing MTA. January 2015. For MTA Arts & Design, artwork created as Art and Bus Cards for display and inspiration for the 2.6 billion annual riders. The artist focuses on his favorite thing about riding the subway: the wide variety of views seen through the subway and bus windows -- the transit system as a kind of rolling art gallery. Viva’s work presents the perfect balance of color and composition along with the eclectic collection of characters who provide interest and detail.
