Hey folks, I need some help with a research project. I'm looking for a particular set of encyclopedias that I had when I was a child. It was a two volume set and it was an encyclopedia/dictionary meaning the front part of both volumes was an encyclopedia and the back half was dictionary. I remember that in the front of both of the volumes there was a lot of information on the American presidents one volume was just simply photographs with brief biographies and the other volume went into much more detail about the President and his history. I also remember that the color of the cover was halfway between a light blue and a dark blue color and had white lettering. I've been through thousands of images on Google Images and I can't find anything that looks like it. The cover had a very slight bumpy/alligator skin type texture to it. I believe they were published somewhere between the mid and late 1970s. My mother bought them from a traveling encyclopedia salesman. I do not remember the publisher's name whether it was Encyclopedia Britannica, World Book, or any of the other ones but going through all of the images on Google I've seen several different publishers and none of them look like what I remember. If anybody can help me out with any information I would greatly appreciate it. Thank you.
