Hi there--I found this t-shirt with a silhouette of Alfred Hitchcock on the front and the text "The 39 Steps" (Hitchcock film, 1935) on the back. The brand is "Hanes." Vintage t-shirts are outside of my area of expertise, and I am wondering if someone who is familiar with Hanes over the years could help me date it. I haven't been able to figure it out based on other online vintage Hanes forums. Photos included. Thank you in advance!
