Nice FDC from USA

I received this wonderful FDC from Alaska, USA. The stamps are dedicated to the 100th anniversary of Modern Art in America. Stamps were issued on 7-3-13. There were 12 stamps in set, there are 5 of them on cover. It is really nice cover.
Inside the cover was another, older FDC

The FDC shows Alaska Native Arts stamp, issued on 20-02-81.
Wonderful!
