Also sorry I have no insight to offer, but agree with Dean and don't take it too the curb. My first impression was it kinda looks like a Bloomrite mark, but when a look I found no evidence to prove it. It is a nice looking Vase none the less and look good in a room of blue motif lets say. I do see many Vase about this caliber at least from a visual standpoint that sells for 19.99 at the thrift shop. Which for something found along the road side is a pretty good deal.
