This is the full comment from a reader:
I peered at the closeup of the artist’s signature on your “Dream Time Music” album and saw it as “Maguire”. Turns out the cover was painted by Robert Maguire, a prolific artist and illustrator. Many websites feature his work. Here’s one: https://americangallery.wordpress.com/tag/robert-maguire/
This is incredibly useful information. I don’t collect Maguire, having only this one and one other that is on a record that I actually own to listen to the music. (Remarkably, about half of my collection is for the music as well as for the covers. 🙂 ) The other half is just for the covers.
Thanks again to CJN for the comment.
