Fabulous piece of ‘90s pop culture by outsider artist J Otto Seibold. This charming address book includes illustrations on dividing tabs and elsewhere throughout the book.

From the Wiki page for the artist:

“James Otto Seibold (born 1960) is an American artist and children's book creator. With no formal art training, he was able to sneak into the art world during the "outsider art" craze of the 1990s.[1] His book Mr. Lunch Takes a Plane Ride, published by Viking in 1993, was the first children's picture book to be created with digital media.”
