I've mentioned before that we have a cabin in the mountains in a rural part of Pennsylvania. And since it is so rural, there has never been trash pick-up. People used to dump anything they couldn't burn into the woods, and I suppose many still do. It is a favorite hobby of mine to uncover these old trash dumps and find things I can re-use. Usually it's old milk pails or sap buckets, or most commonly, bottles.
All of these, except for the largest one in the back, are probably medicine bottles. The ones on the right have a really unique shape, almost like a pocket flask, in that they curve slightly to fit in a pocket. The round one at the left is one of my favorites in that you can see bubbles in the glass meaning it was hand-blown.
This one is marked with the doctor's name. Back in the early days, many doctors (and later druggists) mixed their own formulas, and patented the mixtures (hence the name "patent medicine"). The traveling medicine show became famous for quakery with showmen selling cure-alls that of course did not do a thing. But until medicine became highly regulated by the FDA, it was always "buyer beware"!
