My Sesame Street Yearbook 1985 is an interactive Sesame Street book. On each page, an illustrated Muppet character asks the reader a question, and the reader is encouraged to respond by writing down the answer, drawing a picture, or pasting personal effects into the book. The information compiled by the book ranges from basic facts, such as birthdate, height and weight, to the more open-ended, such as how the reader would spend a day with Ernie and Bert.

Other Muppet characters featured in the illustrations include Big Bird, Grover, Prairie Dawn, Betty Lou, Cookie Monster, Oscar the Grouch, The Count, Snuffy, Sherlock Hemlock, Grover's Mommy, and a handful of Twiddlebugs.
