In 1950 Charles M. Schulz introduced to the world a brilliant comic strip with a young boy and the coolest Beagle dog around, Charlie Brown and Snoopy! Soon the comic strip spawned multiple hit cartoons, like A Charlie Brown Christmas, It's The Great Pumpkin, Charlie Brown, Charlie Brown's All-Stars, and, Be My Valentine, Charlie Brown. The Peanuts pajama set features a large front printed design of Snoopy laying out on his red doghouse with Woodstock below and the script saying Happiness is Sleeping In! The pants feature an allover striped design of Snoopy and Woodstock. They are made of an extra soft and comfy 100% polyester fabric. Look for the trademark Peanuts logo tag on the inside of pants and the shirt collar for assured wear and product! See the size chart for exact measurements. These are the best!
