When I first saw these photos, I figured they were costumes for some type of alien invasion movie or some type of space suit attire.
These are actually old fashion diving suits from the 50s and 60s.
They are made of very light material.
They sure look different from what divers use now. (Noting like wetsuits!)
I am not really sure why the diver is posing for a photo with his wife in his suit.
It sure makes a funny picture though.
