Colorite Straw Hat Yellow Dye Bottle with Box

Not only does this include both the box and bottle it also has a bit of liquid in it. Not only that but anyone can use it!
This was made from 1915-1929 although I got that off an eBay seller so it isn't etched in stone. Although from other pieces I gleaned off the net my guess is it seems accurate. I saw a newspaper ad from 1919 so it seems reasonable.
Anyway once your jaunty straw hat starts to look dingy this can spruce it up. Also works on other straw products as long as they are yellow.
