This spider web design bottle has a smooth, flat, oval on the lower portion of the body which I'm sure once held a label of sorts. On the back of the bottle there is a significant oval shaped flat area that has the web design like the rest of the bottle. The makers mark on the bottom indicates that Atlas made it. I do not find any spider design in any of the webs. Does anyone have any information about this unusual bottle such as what it once held and when was it manufactured? Many thanks.
