The 1991 Matchbox Collector's Edition Catalog is exactly what it claims to be, dedicated to the collector! There's a Days of Thunder collection right in front.
The "Con-nect-ables" page shows us that Matchbox figured out how to market the mix and match idea for toy cars.
There's a page dedicated to Matchbox's "Carousel Collection". Even a young Frankenstein gets in on the fun with the "Monster in my Pocket" page.
If nothing else take a look through this mag to see the awesome playsets, along with their super background setups. Unless you had a hobby store near by as a kid, you only dreamed of having such toy car setups!
