Editorial comment only. This outfit approx 8-9 years ago attributed a collection (approx 20) of vases marked DK as Durand Kimball & of course they were all marked with the well known PK logos (where admittedly the P can look like a D)plus the glass was nothing like Durand Kimball production. Always nice pics & good stuff but for such a well known operation we on this side of the pond do not pay much attention to their in house estimates. Will say though that it filtered down the pipeline that they withdrew the entire collection the day of the auction so they are on the up & up. Was a bit amusing though as a year later one of the many antique guide books published yearly had about 5 pics of the withdrawn lot ided as Durand Kimball attributed by this op.
