African Shield, Sowerby
These small vases (about 4 1/4 inches tall) probably came with the metal flower holder shown, but are seldom found with one. Only known in marigold, they sell for between $20 and $30 without the wire grill, $40 to $60 with one.

These are also found occasionally found with a lid with a spoon slot so they could be used as a condiment jar.
