The Letter Getter is a Hot Wheels tribute to a classic American vehicle, the U.S. Mail truck. It was first released in 1977 with an unpainted metal base. In that first year, the Hong Kong casting could be found with either redlines or blackwall tires. I found my first Letter Getter at an antique store awhile back, but the lack of remaining tampo left me wanting a cleaner model. So I recently picked up this black-plastic base version from 1979 on eBay.
