For the rest of today's Sunday Stamp Sunscenes, go here.
USPS tends to release stamps that celebrate the existence of each state on their 50th, 100th, 150th etc anniversaries.
Louisiana was admitted to the Union on April 30, 1812, a mere 9 years after the land was bought from Napoleon as part of the Louisiana purchase. A stamp celebrating its bicentenary was issued in 2012 featuring a photograph of the sun setting at Flat Lake taken by C C Lockwood, a Louisiana photographer.
The cost of priority mail went up on January 17 from $5.75 to $6.45. This warranted the issue of a new stamp for this rate. The stamp features La Cueva del Indio, a cave on the north coast of Puerto Rico. The cave is famous for its many petroglyphs, and is part of a Natural Reserve. The stamp artist is Dan Cosgrove. It doesn't specify in the stamp info, but based on the cave's location this would have to be a sunset as well.
You can see here the relative size of these stamps. The state stamp is the standard commemorative size.
