Above you will see a fine Porsche 911 Turbo cast in 1:64 scale, made by Tomica. Below, you will a pretty good copy of the same exotic car, only this one was made by Welly.
Here's an ambulance model made by Hot Wheels, called an "American Ambulance." Below you will see an almost identical copy, even down to the tampo design, made by Maisto. You tell me, was this intentional or not?
This is the Deora, made by Mattel in 1968. Below you can see a copy of it from Argentina. It was made by a company called Muky, and as far as I can tell, they named it "Furgon."
Pretty similar, eh? If you like copies, some of them are quite well made and sport features sometimes not found on the original versions. So, keep your eyes open as they "send in the clones."
