Maybe something like register the logo again and create own our legal T-Shirts.
Any Trademark lawyers friends around?
A difficult question. This website might provide some of the answers. And it might also depend per country if you can use a trademark that has expired.
There are a lots of shades or grey in this discussion what is legal todo and what not.

From the website above:
"If the dead trade mark is a logo, the copyright in the logo could still belong to a third party such as the original designer. Copyright can last for the life of the author plus seventy years and you may have to conduct additional research if you want to use an existing logo and perhaps secure a written assignment of its copyright if you can locate the original owner."
