When traveling to my ranch in South Texas, I stumbled upon an old Dr. Pepper machine. It was old, dilapidated and sitting in front of an old house, as if it served a purpose, almost guarding their front door. It had huge buttons (9″ or 10″ x 3″ish in size) for each soda. It made me think of how the logo has kept its general look and feel throughout the years (unlike that of other sodas like Pepsi), etc.
The drink, invented in 1883, is said to be named after the father of a daughter whom a pharmacist was trying to impress. Generations and generations later, the general font treatment and color scheme remain the same.
