Buster and Monster Fun 25th March 1978
Theres nothing like a old house full of secret passageways..and fighting off intruders like the olden days ..and I'm sure he finds treasure hidden away in the end and can restore the home to former glory..

The Buster website doesn't know the artists name...my guess its Mike Western?
Whoever did draw it..they did a great job...
