An easy way to find out what font is used on the back cover is to crop out a word and save it as a separate image in its raw form. Then, use myfonts.com and go to whatthefont. This will identify the letters in the image you uploaded. After you double check the letters it detects, you click on "Continue" and it will give you a list of matches based on your image. That's what I do to find out what fonts are used on the back cover. If I can't get an exact match, I download a font that is very close to it. That's what I do when I retype text on all my covers.
