Sunflower Vase, Imperial
I know little about this 5 1/2-inch tall red vase other than it has an IG mark on the exterior base.

Examples sold on eBay in 2008 for $18 and $64.

In 2013, a red example sold for $30 at a live auction.

However, the red 5 1/2-inch vase at the left sold at an online auction in 2020 for $650.
