Thanks for your help! It’s great to learn a little more about the shirts and get an appraisal. I think I’ll be holding on to both as personals, they were definitely my grandpa’s favorites and pretty iconic to his memory.

Thanks in advance for the help, much appreciated! My late grandfather absolutely loved Marilyn Monroe. He owned quite a bit of Marilyn related merch, including the tee in question. The licensing caption dates to 1997, and the Gildan Heavy Weight tag appears to be the same year, or at least late ‘90s...
