Very unusual design by Jack Kinkelaar. In excellent condition. Its unique design is highly collectible. Signed "Kinkelaar". Measures 1.5 inches by 1 inch. This is likely an earlier piece given its small size and copper backing. Many of his pieces incorporate fantasy / extraterrestrial / imaginative imagery. For example Jack Kinkelaar essentially created a miniature painting on this enamel-on-copper brooch, one of his long-standing and continuing artistic themes of fantasy landscapes incorporating outer-space elements with earth-bound elements. A great addition to your brooch collection.
