Barney's Alphabet Fun! is a 1998 children's picture book that was written by Guy Davis and photographed by Dennis Full.
The book was originally released in conjunction with the then-upcoming film Barney's Great Adventure (visible in the logo itself). The book was later reprinted under Scholastic and HIT Entertainment when Barney was purchased by HIT, with a plainer, non-related logo.
It's a great ABC adventure with Barney. Come along on a Super-Dee-Duper trip around the farm as children learn the letters of the alphabet in an exciting and memorable way.[1]
Ralph makes an appearance alongside the other animals seen in Barney's Great Adventure, but another breed of dog is used to represent him (a Bernese Mountain Dog instead of a herding collie).
