This is an actual Harley Davidson advertisement in a magazine from 1966. Notice the Harley Davidson logo on the right side of the advertisement. I think they also used this same logo as a motorcycle gas tank badge in the past. Notice the same logo appears on a t-shirt Harley Davidson sells on their website as of 3/18/2025. Harley Davidson brings these old designs back, and I think they've been pretty popular. I've seen the same logo used on several products, in fact, I own a different t-shirt than the one in the photo below, but with the same logo.
