1. Stamp unveiled

The U.S. Postal Service has unveiled its new World Stamp Show forever stamps.

The nondenominated first-class stamps were officially issued Thursday at the American Philatelic Society's annual Stampshow in Grand Rapids, Mich. 

The stamps, which will be sold in panes of 20, honor the once-in-a-decade event that will take place in New York City next spring.

The words "2016 World Stamp Show/New York City" circle a small star in the middle of the stamp, with "USA" at top and "Forever" at the bottom, surrounded by a variety of vintage-looking decorative motifs.

The single design is rendered alternately in red and blue through the sheet. The stamps will be printed by offset.

The top margin of the sheet reads "Come explore exciting new worlds at the World Stamp Show—NY 2016" and gives the dates, May 28 to June 4, 2016.

2. More from Grand Rapids

There was a very cool live Periscope broadcast from Stampshow 2015 this morning.
