Edwardian Womens Straw Boaters Tilt Hat - Antique 1910 to 1930 "Betty Coed"

I live in a once booming railroad town in rural WA and there is this amazing Art Deco Theater that is being renovated even though our population is now near 500. I was asked to do some appraising on old costumes and allowed to purchase what I want from a bunch of items. I grabbed some amazing things and some damaged things but these hats I found are my pride and joy. This amazing Betty Co Ed Turn of the century to the early 30's based on brand and style. This straw mini tilt hat is stunning. The workmanship is great. Its in very good vintage condition There is no damage to straw I can find. The elastic chin strap is a bit stretched ( like we all are at over 100 yrs old LOL ) The color is really interesting. Its black but also a weird brown undertone. Changes colors in light. It is in good solid shape but again, very old and don't expect new. It is a rare find in this condition and with such adornment This hat I would guess dates from early 1900 to 1920's and amazing. Straw Portion of Hat is about 10.75" across Bow is apx 12.5" tip to tip
