I posted about this back in 2019, but I did this with a photo and returned it to a very appreciate family. Obv you are not planning to send the card back, but it might be a fun reunion.
Here is my story:
I picked up a few photos from Dennis (photomoto) and he tossed the following snapshot into the deal for free.
I saw the writing on the back and decided to go hunting. Lancelotti, Curacao, and the army were where I found some traction, as I found some info in an army database and that led me to this online memorial:

A bit of time going through Facebook, Google, and online White Pages in the area led me to the Facebook profiles of who I believed to be Daniel's son and grandson. The former never replied, but after a few messages the latter did. It turns out that he showed the photo to his grandmother, Daniel's wife, and she was thrilled to see this never-before-seen photo of her late husband. I immediately dropped the photo in the mail - it is now back where it belongs.
And I got a very nice hand-written note from her about how much it meant. I assume the photo belonged to one of the other guys in it and she never knew it existed.
