Hello my name is Glenda, .Are you trying to find out if this T Shirt was actually made for the Grateful Dead? .
Do you mean Grand Funk? Or Grateful Dead?
Are you wanting to know if the Grateful Dead did t shirts with the Astronaut on them? Or are you wanting to know what album etc?
I am not finding your exact t shirt, I did find T Shirts with Astronauts from their Fare Thee Well tour.
But, I cannot find this exact t shirt.
On the Shirt you have? No not that I can find. I only found the one shirt with an astronaut and it is the one from their Fare Thee Well tour. This shirt could have been made for that concert, since they do have one other one out there with with an astronaut on it from that tour.
