I really like this image, not only because I think the man in the photo is being funny, but also because I knew the man in the photo and as a kid, I would have never imagined him posing like this for a picture. That's only because little kids can't picture older people goofing off.
I knew Mr. Sparks when he was much older than pictured here. He was the father of one of my mom's friends. He was a very kindly old gent that I felt very at ease around. Many years later, his daughter gave me a group of photo-postcards, that included this one, of her dad and a group of other fellow field geologists. She knew I collected postcards and was generous enough to give me this set.
The group was on an expedition — location unknown — looking for uranium. I am assuming that this picture was taken in the late 1940s or early 1950s. At the time, there was a great call to find deposits of the mineral and some pretty good money could be made at it as well.
I can understand them wanting to document the expedition and perhaps make a few postcards of the pictures to send back home to family; an interesting time. However, this is the only picture in the set of someone being not so serious. I think Mr. Sparks would have a chuckle to know that I am now sharing his antics with you.
