Rib and Panel
I've seen this pattern in a number of different configurations and at least two different base sizes. The vases once sold in the $25 to $40 range, but in the late 1990s a book reported them to be variants of the much more rare and desirable Imperial Colonial Lady--which they are NOT. These were probably made between the 1930s and 1950s. After the misidentification, the prices rose to closer to $100 or so but have since fallen back to the earlier range.

Spittoon-type whimsies similar to the one shown above left sold in 2007 for $55, $165, and $300 and in 2009 for $40 and $110. In 2013, an example sold for $45. In 2016, a similar example brought $55.
