MLP as it would have likely looked if it were created in the Golden Age of Animation, circa 1930. Honestly, I think the proportions look a bit strange, but on the other hand most animation from the time period looked like that. I do like the accuracy of the depiction to art of that era, though. I think it could have made for a pretty fun cartoon, too. Makes me wonder how the rest of Equestria would have differed from the version we saw in FiM, due to the time period being so different.
