So on Tumblr, there is a site called WTF Bad Fantasy Covers, which posts covers of fantasy books of varying quality. This particular week, they are basically doing furry books. A few days ago, they posted this set of books by Stanley Rand (which can be found on Amazon.com). Any of the covers look familiar? Well if they do, that's because they are probably well known pieces that have been posted on-line. One person has been in contact with at least two of the artists, recognizing the images, and received word that no, they did not give permission to the author to use their art for the covers.
