Cartoon Stamps for Kids' Mail and Parties
Character stamps fit best on mail going to a child or coming from one: party invitations, thank-you notes, letters to grandchildren and care packages to camp. Plenty of adults who grew up with these shows use them on everyday letters too.
Message Monsters suits younger kids, with four monsters drawn by children's book illustrator Elise Gravel. The border holds peel-off speech bubbles, hats, crowns and stars to stick around the stamp, so keep it intact until the stamps are used.
Nothing on the monster or droid designs is seasonal, so a sheet bought for one birthday keeps working all year. A sheet of 20 covers roughly one small party, counting invitations and the thank-you notes that follow.
Character Stamps for Christmas Cards
In A Charlie Brown Christmas, Charlie Brown holds his sapling, Linus kneels by the bare tree and Snoopy skates with the other kids. One frame shows Charlie Brown checking an empty mailbox for a card, a fitting picture to put on an envelope.
Rudolph, the other Christmas booklet here, draws on the 1964 stop-motion TV special rather than the song. Both Christmas designs come in booklets of 20, and most families sending cards buy several.
Peanuts fans have a non-holiday option too: the Charles Schulz centennial set carries birthday cards and letters to grandchildren year-round.
How Many Stamps Come in a Sheet
Most designs here come in sheets or booklets of 20, but two use smaller panes, which changes the math against a guest list.
SpongeBob SquarePants stamps, issued in August 2025, come in panes of 16 with four designs, including an ensemble shot with Patrick, Sandy Cheeks, Plankton, Mr. Krabs, Gary and Squidward.
Scooby-Doo! comes in sheets of 12, showing Scooby watering a flowerpot for the Doo Good campaign that pointed kids toward environmental work, hunger and animal welfare.
Each cartoon stamp covers a one-ounce letter: $0.82, in effect since July 12, 2026, on the USPS price list. Heavier cards and square envelopes need more postage.
