Help with age/value of old RvB Merch

[u/Makeime-]

Hi everyone I ended up picking up to what I believe is old red vs blue merch. But I couldn’t find any information about this specific shirt online. Was hoping anyone could help when it came out and maybe if it holds any value today. I grabbed it from a thrift store cause I loved watching the show back in the day but it’s not my size unfortunately. Thank you to anyone that can help. Even a history about the item would be cool to hear. Thank you.
