From Dean’s Mother Goose Book of Rhymes, illustrated by Janet Grahame Johnstone and Ann Grahame Johnstone. This book was published in 1977 but it was a compilation of several volumes from throughout the 70s.
I bought the Omnibus of Nursey Rhymes in 2013 and this looks like a similar artist. That book was amazing to me as a child and I'd just get lost in the illustrations.
Finbar likes when I pretend he is a bagpipe! He snuggles under my arm with his front paws on my knee and I gently squeeze him with my elbow while I blow into his tail... not sure who is odder of the two of us!
I love this style of drawing. Where a non-human animal is anthropomorphized without being altered, it just looks like a real cat doing something plausibly human (no offense to furries, keep doing your thing homies!) I just find this especially cute and charming
