Looks like an athletic heather grey tee of the TPB. If you notice carefully the name resembles Mt.Rushmore! The shirt makers claim that this name is a funny take on this iconic mountain. A funny tee made from 100{4be404f03870929f38922bf132858a35c6db266f472178b8240f995958b07430} knit cotton.
The one thing that I have realized over the years is that the TPB series is a line of extremely funny t-shirts for men. Sure, there are tank tops that women love, but the collection offers many scintillating prints for men. That, in my view, is not a discrimination but simply because of the connectivity with the movie.
If you are looking for an extremely comfortable tee, the Kushmore tee will suit your requirements. This is a classic heather grey background that works well for almost everyone in this world. I bet, you have more than 2 such shades in the wardrobe.
By the way, there is another information about the illustrated book of Trailer Park. That book about the making of the Tv series boasts an extensive coverage of rarely seen images in HD print. I could have bought that in one go but there is some amount of saving that I need to preserve. But will surely get it in due time.
