Loganberry - Imperial
These dramatic vases are 10 inches tall and have a 4 1/4-inch base. They have been reproduced; the old vases have a starred base, the new ones an IG logo on a stippled background. Some are also seen with a plain base--some of which may be old. An additional clue is that the new examples have ruffled tops. Shown here are classic-era amber and purple examples.

Other colors include clambroth, green, Helios, lavender, marigold, olive, smoke and teal.
