We've all seen a "tie-in". This is a book, toy, game, etc., that's based on a movie or TV show.
The original Maverick series generated plenty of tie-ins, some of which (e.g. comic books) you've seen on this blog. There were also Maverick vests, string ties, cowboy hats, cap guns and holsters, wallets, school-bags, coloring books, plastic figurines, phonograph records, paint-by-number sets, and even Halloween costumes.
Most Maverick merchandise was popular--and profitable. Reportedly, at least a million dollars worth of Maverick-themed items had been sold by the end of 1958.
Jigsaw puzzles were another tie-in. I've seen a few Maverick puzzles, including a couple printed with photos of JK and James Garner as Bart and Bret. I've also seen one with a painting of Bart riding a wildly bucking black bronco.
Here's another jigsaw puzzle I hadn't seen before. It's now part of the Kellection:
It depicts Bart on a leopard Appaloosa (where's Goldie?) galloping through the hinterland, with Cousin Beau following closely behind on a bay.
A label on the puzzle says it's "For Developing Coordination and Motor Control". Gee, I'd better practice putting it together several times a day, then! ;-> No, I'll just stare at it instead. :)
