The James Bond Jr. concept came complete with lots of official merchandise, including these six paperback books by John Vincent. Interestingly, the copyright pages reads "Copyright © EON Productions and Mac B Inc 1992", but also adds, "The use of M and James Bond Sr. is by agreement with Glidrose Publications, Ltd." It's also worth noting that the publisher, Puffin, would later release the successful Young Bond series by Charlie Higson.
The cover art and titles are pretty fun, but I admit I've never read them. But they are official and, like it or not, a part of the Book Bond legacy.
Check out the opening credits with the official James Bond Jr. theme song, which really isn't half bad. Maybe I do need to read these.
