I’m looking for a children’s book that my partner used to have 30 years ago – she possibly even got it from her mother.

It’s a story that follows a boy on a journey through nursery rhymes – he goes on a walk and meets various nursery rhyme characters on the way. She can definitely remember him meeting Humpty Dumpty and she remembers at some point the boy visits a petrol station. The book is very well illustrated apparently and she thinks the cover may have been green but she’s not 100 percent certain on that.
