Set of‎ 4 White Figurines 1 Clown 3 Children

Used figurines boy with dog, girl with dog, boy with cat and a clown. There are no manufacturer markings on any of them but they do have a letter on the bottom of each. Some of the paint is chipping off on all of the figurines. I do believe they are Japanese because of some of the painted letters on one of the figurines. Would be a great addition for any collector!
