Vintage T-Shirt Forum & Community Authentication Appraisals

This t shirt comes from my late brothers estate, who was a music journalist in the 70s/80s.
It would have been given to him with press pack?
It has no label and I have not seen the Queens head placed liked this.
Has anyone got any knowledge about it?
Thank you

My go to expert had this to say about it:

"The Pistols / Queen logo, it's not an official Seditionaries tee. It was printed as a prize

for a Record Mirror competition. I've seen people try and sell them before, but buyers don't go very

high - perhaps 100 to 200."

Thank you for your help, am I right in thinking that it is still a 70s t shirt?
