The photo on the bottom is an MG Midget, and the one on top is its predecessor. Both were produced by Morris Garage (Hence the "MG."). Morris Garage, a British company, started manufacturing cars in 1924. Unfortunately, they went bankrupt in 2005, although I read that a Japanese firm has bought them and will start production soon (if they haven't already started).
