These vintage solid copper kitchen miniatures are typically used in doll displays, as they're larger than normal dollhouse miniatures. I've shown a quarter in some of the pictures for scale. The largest is the Grecian style urn vase at 3-5/8 inches high. Next is a wide handled basket, nearly as high as the vase and 3-1/2" diameter at the rim. The tall colander may have been intended as an incense burner (the bottom opening is too small for most cone incense though, so maybe it's some type of kettle grill). The last two items are a handled vase or vessel and an urn or jug, 2-1/4" high.
The items have some tarnish, easily polished away. The basket rim has a couple of short, deep scratches. The handled vessel is marked with the number 12, the other pieces have no markings.
