Carnival Glass Amethyst Maple Leaf Water Set (Pitcher, 6 Tumblers) Dugan?

Description

I know this pattern is "Maple Leaf" and that pattern was made by Dugan.  That said, I know there are reproductions around.  So, I am not stating for sure who made this set.
There are no cracks or chips and everything is in great condition.  There is some variability in the tumblers when it comes to coloring--the iridescence is more pronounced on some.
This is definitely a set with a striking appearance--the geometry and large leaves really give it texture and presence.  The coloring is almost metallic.
One tumbler has a spot inside the bottom where the finish either didn't deposit perfectly or has come off.  You can see it in the pic alongside another tumbler for comparison.  This is not noticeable from the outside.
Shipping will be either USPS or UPS regardless of what the eBay shipping calculator shows.  I will cover the shipping and choose the best option to get it to you in the safest way.
