Love the 64 Venezuelan! I'm afraid I'm not much help with the postcard however. It looks to me, to be early to mid 70's (1971 perhaps?)- definitely pre 1974 when they the Sox started wearing the red and blue hats before moving to the all red hats in 75. It Doesn't really look like the team issued postcards from that time. I believe there were bot a color and black and white set, but both had full photos, not the cropped heads.
I don't think I've seen another like it, is the back blank?

Thanks Scott. Yes, blank back and thinner cardboard stock. I looked at the image under magnification looking for sign of it being some kind of photocopy but saw no signs of that.
