It may be heretical of me to say so, but I've never particularly liked Elvis Presley's songs. They just don't appeal to me. Nevertheless, he's probably among the top five iconic American singers of the past century, and looks set fair to remain at that pinnacle long after I'm dead.
It seems he was also a firearms enthusiast. Two of his engraved, inlaid revolvers were auctioned in 2017. Click either image for a larger view.

I've no idea what price they'd fetch today, but I'd be surprised if it's less than six figures apiece. That German engraving job is world-class by any standards, and the gold inlay is spectacular.
Er ... since Elvis was a musician, dare I suggest that his revolvers would be a note-worthy acquisition? They'd lend tone to any collection!
