Similar to several other patterns having eight ribs, Dugan's Wide Rib is most easily distinguished from others by the rather bulbous tips on the top and the large, 3 3/4 inch (and larger) base. As can be seen by the photograph, these vases can be shaped in different ways and may have any twist going in either direction. Examples with a twist are sometimes mis-identified as Spiralex, a similar Diamond pattern with eight ribs.
