A few years ago while doing some thrift store hunting I came a crossed this matchbox Plymouth Prowler Concept Vehicle with Arizona Diamondbacks logos on it
It also has a special logo on the rear for the 1998 Inaugural Season
Now for several years Matchbox had a contract with MLB to produce different die cast with team logos. From what I can find after Mattle bought out Matchbox in 1997 1998 was the final year of the MLB cars before other brands and off brands produced them. What I also like about this is not only was it the D-Backs first year in MLB but 1998 is when I started to get into collecting not just opening them up but leaving them in blisters or properly storing them.
