I found this on Pinterest- apparently posted by a model who posed for one of the Hardy Boys cover art drawings. Can anyone figure out what book this might be? Interesting...

Reminds me of The London Deception.
Hmm- it does bear some similarities. However, I should have also mentioned earlier that the guy who posted the photo said that this photo shoot is from the 1970s. So I am guessing it would probably be from the one of later Grossett & Dunlap titles of that time, or maybe even from a foreign cover art, like the British Armada books or something.
It doesn't bear any resemblance to any of the Hardy Boys from the 70's, 80's, or 90's. It might've been an unused shot.
I guess that's true. Or maybe it was an interior illustration rather than cover art?
Here's something else I found that's kinda related to this topic.
Here's the format used for The Hardy Boys Mystery Stories during the latter end of the Digests run- a mockup for #170 Kickoff to Danger before the cover art had been finished. I just found this at random online and thought it was neat. :) 8)
