Vintage children’s book with matching alligator plush stuffed animal

Children’s book Lyle and the Birthday Party written by Bernard Waber with matching stuffed animal. The book is vintage in good condition with no coloring marks, rips, etc from 1966 The stuffed animal is not vintage, but works well with the Book as a mascot! I recently washed and dried the stuffed animal so it’s very clean and from a clean home. The book is a story about an alligator who experiences jealousy when the child he lives with receives a birthday party and He didn’t. The ending msg. is inspirational I think would help teach about jealousy and waiting your turn for things to come.
