A great book to spend an hour or two browsing through.
R. Crumb's, "The Complete Record Cover Collection." Full of his drawings and graphics for various record covers, mostly of old Blues, Country and Jazz recordings from the 1920's and 30's. Many obscure musicians and recordings. It's fascinating pausing and lingering for a moment or two, over each illustration before turning the page and discovering what's next. It causes me to want to search out each and every record.
Goodreads
An example of one of the many unique, imaginative and colorful images that fill the pages of this book. I've never heard of any of the musicians on this record but would happily give it a listen and add to my record collection based on the cover art alone.
