Summertime smells like sunscreen, barbecues, and—starting June 20, 2018—postage stamps. That's when the United States Postal Service debuts its first line of scratch-and-sniff stamps in Austin, Texas with perfumes meant to evoke "the sweet scent of summer."

The 10 stamps in the collection feature playful watercolor illustrations of popsicles by artist Margaret Berg. If the designs alone don't immediately transport you back to hot summer days spent chasing ice cream trucks, a few scratches and a whiff of the stamp should do the trick. If you're patient, you can also refrain from scratching and use them to mail a bit of summer nostalgia to your loved ones.

Since it was invented in the 1960s, scratch-and-sniff technology has been incorporated into photographs, posters, picture books, and countless kids' stickers.

The first-class mail "forever" stamps will be available in booklets of 20 for $10. You can preorder yours online before they're unveiled at the first-day-of-issue dedication ceremony at Austin's Thinkery children's museum next month.
