Frosted Block Variant, Imperial
Imperial made this vase in the Meadow Green (shown here) in 1980-81, pink in 1978-82, and amethyst in 1981. It is called a Variant because, unlike Imperial's original Frosted Block, this pattern does not have the stippling within the squares. This one sold on eBay in 2004 for $7; a pink example in 2004 for $32.

Imperial also made a 5 1/4 inch bowl in this pattern in pink.
