That old Cologne or Toilet water may have been painted originally. I have an open pontilled one like yours I dug and before I washed it I scetched the paint on it. It was in really sad shape and not all there so I washed it off. Here is a picture of the sketch I did. The "W" stands for white background. The "C" stands for clear . The yellow colors were gold paint.
I went back to the garage sale again. The woman is going to be open 4 days a week throughout the summer. Today I bought another crude amber flask and 2 blob top soda's and a h fox and co inc, figural fox bottle and one that say's hydrozone on it.

It's really thick amber glass with a tiny mouth. It has stretch marks on the neck and the seams almost feel like they are off a little. Anyone every hear off it or know the value of it or what was in it. Jason
