Gotta love Dr. Pepper! Here is a fun pre-worn, promotional size LARGE, black T-Shirt that has graphics on the front of the T-Shirt that reads...Dr. Pepper - Trust Me I'm a Dr (Doctor) with the same on the back side with a larger graphic.

The T-Shirt measures 22 inches across the chest measured under the arms and from the back of the neck band to the bottom hem is 28 inches—just a little short. No holes or stains and 100% cotton.

And just so you know..
As of 2009, the slogan of the product is "Drink it slow. Doctor's orders". Advertising supporting the slogan has celebrities with famous relations to the word "doctor" (Dr. Dre, Julius "Dr. J" Erving, Gene Simmons (writer of the Kiss song "Calling Doctor Love"), et al.) or who played fictional doctors (such as Neil Patrick Harris or Kelsey Grammer) endorsing the beverage. The ads culminate with the celebrity stating, "Trust me. I'm a doctor", followed by the new slogan appearing onscreen against an ice-cold glass of Dr Pepper.
