Vintage Sunday Comics Mickey and Minnie Mouse‎ top

Collectible unique vintage Mickey and Minnie Mouse oversized t-shirt. They are back to back with a flirty look and Mickey is holding a bouquet of flowers. The hearts above them are all velvet material. The stamp at the bottom of the graphic is Walt Disney Productions. The brand is Sunday comics. I am not sure if this is an oversized t-shirt or a nightshirt. The pit to pit is 22" however it shows that it is a size small. The back of the shirt is the back of Mickey and Minnie as though you can see them in a full 180 degree view. I believe this is a single stitch. The flaw is that the neckline binding is loose on part of it on the front of the shirt. It could be repaired or re-sewn. I could attempt it but I am a very amateur seamstress.
