It seems like it may be from an "old" book. I did find it at the following website: https://wakandalegendbasenji.com/basenji-in-africa/ The site owner should be able to tell you something about where they found the photo.
The question about the doggy smell is a good one - basenjis do not smell like dogs. If you stick your face right into their fur the comparison is like sticking your face into a nice clean healthy cat - warm and not really a discernable smell. Except their feet. Their feet smell like Fritos sort of.
