The Winnebago Post Office will begin selling these on July 5th. 

USPS.com - The digital illustration on this stamp is a symbolic scene that shows three first responders in profile, facing right, as they race into action. From left to right, the first figure is a red firefighter carrying an axe. The second figure is a grayish-white EMS worker, with the EMS Star of Life visible on her cap, upper arm, and emergency bag. The third figure is a blue law-enforcement officer shining a flashlight toward unknown danger ahead. The dark background and signs of smoke in around the figures suggest the wide range of situations that demand the immediate attention of a first responder.

The stamps will be on sale for the regular price of 55 cents per stamp.

Supplies are limited so make sure you don't wait too long.
