Inspired by the quick success on the earlier thread asking about a children's book, here's one I've been wondering about for decades.
Can anyone remember any book for little children, where something like Scuffy the Tugboat, but not Scuffy the Tugboat himself, goes to Venice? Art quite similar to Scuffy, possibly a Golden Book. I'd always thought it was Scuffy, but turns out he didn't make it out of the USA...
It was a favourite library book when I was very young - I can remember the pictures of Venice quite clearly. A discussion about it retold in family history dates it to 1979 or earlier.
