Thanks for all the comments and info, guys! I was told it was Amstel, but it totally has the Struzan look. The guy who gave these to me was VP of Marketing with Paramount over 30 years ago, so I don't blame him for forgetting a few details.
However, he did get to visit the sets in England, as he was/is a good friend of Frank Marshall. I love the t-shirt because it marks an important piece of Spielbergian history, sort of saving his career by finishing a film under schedule and under budget.
