I've got two, one mint and boxed. I've also got the Corgi Junior's version. Mattel also did one recently on a similar scale to the larger Corgi car, but it didn't have Batman & Robin figures unfortunately. When you compare both versions, you can see that the front of the Corgi BM is slightly 'stunted'. (The same is true of the Aurora model kit apparently.) Still a great toy 'though.
Awesome ad! Great find, thanks for posting.
