Vintage 70's Heart Dog & Butterfly Tour Raglan T-Shirt original from concert!

I purchased this shirt from their concert at Notre Dame in South Bend, Indiana, back in the 70s.
(Great concert!)

It's been well worn, including fading of the size label.  
I'm thinking it might fit well for a medium based on the measurements.
Please check the measurements below for comparison of a shirt of your own.

Note the stains on the sleeves and the hole in the armpit.

Let me know if you have any questions or need additional photos.

Still a nice solid addition to your HEART collection.

Measurements with Shirt laying flat:
18 inches armpit to armpit; 
12 inches armpit to end of sleeve; and
22.5 inches top of back collar to bottom of Shirt.

Again, please check the measurements.
Thank you.

I also have a bed sheet, red in color, in the shape of a heart, with Heart written across it.  Original from Ann & Nancy Wilson's hotel room.
