This is an interesting picture of Elon Musk at 17 years old. He is wearing a T shirt from the Mid Valley bank in Weslaco, TX. Weslaco is a town very close to the Mexican border between McAllen and Brownsville. If he is 17 at the time that would put this picture somewhere around 1988 or 1989. Right around the time of The Believers Cult murders in Matamoros, MX.
