Vintage Wooden Collapsible Toy Dog Push Button Bottom

Description

Works as it should, collapses when you push the button on the bottom. The paint on the wood in the front the green looks like it's worn off some because I can't tell what it actually is. The dog has a little bit of green on his nose so I'm thinking maybe this green paint is not even supposed to be on here at all and maybe a kid did it but I could be wrong. Anyway, shows normal where for its age. Questions welcomed and thanks for looking.
