This is a 80s/90s picture book with no words or few words. A female pig runs wild at an amusement park, it could be a department store rather than an amusement park, trying on hats and eating lots of ice creams and rides the rides and possibly gets chased by a policeman (for having no money to pay for ice-cream?) before finding true love with a wild boar and having several piglets at the end of the book.
Stump the Bookseller
New format, same book stumper solving.
Might be something by John S. Goodall, who wrote a bunch of wordless picture books, some of them about (anthropomorphic) animals. I only know one of his ‘Paddy Pork’ series and that one doesn’t match this description, but the others are a possibility.
Hi! I am the OP. Persistent & random googling has paid off. I found it: Pig in a Muddle by Mira Lobe and Winfried Opgenoorth.
