"Johnnie & Mack by the railroad track, the world's largest and that's a fact!" Their address at the time was 74 NE 20 Street so those were different railroad tracks before they moved by the tracks on NW 36 Street. Even back in 1960 someone at Johnnie & Mack "Se Habla Espanol" judging from the sign at the top of the photo. Thank you to Ivan Feller, son of the founder, for identifying the folks in the photo. Thank you to George Young for contributing the image, which was from the 1960 Mahi, the Miami High School yearbook.
