Vintage Margaritaville 15th Anniversary T Shirt by Caribbean Soul

Here is an awesome vintage T-shirt from 1998 by Caribbean Soul. 100% cotton and made in the USA. Blue shirt with graphics on the front and back. I Google searched for this one and nothing came up. So maybe it's a rare design. Medium weight, soft and comfy. It's in amazing condition with tons of life left. The tag says Large, but here are the measurements taken laying flat. Please refer to the last pic to see how I measure shirts. 

Chest (armpit to armpit) 20"
Shoulder to end of sleeve (including cuff) 8"
Length 26"
