From the April 2nd Postal Bulletin:

On May 18, 2015, in Anaheim, CA, the U.S. Postal Service will issue the Missing Children stamped envelope set of 10 envelopes with seals, Forever First-Class Mail priced at $9.95, in pressure-sensitive adhesive (PSA) #10 stamped envelopes (Item 882102).

This spring, the U.S. Postal Service issues two different sets of 10 stamped envelopes including seals. The artwork on the stamped envelopes is based on the 2015 stamps celebrating the same subjects. The Missing Children set includes 10 stamped envelopes showcasing a photograph of a bunch of purple Forget-Me-Nots next to a lone flower with text on the top of the stamp that reads “Forget-Me-Not” and text on the bottom that reads “Help Find Missing Children.” The seals included in each of the sets complement the stamp designs.
