2 Vintage Cobalt Blue bottles, 1 is for medicine (I think), it has a tin screw on lid (quite rusted).  Size is approx 5"tall.  Made in USA marked on bottom.  The Other one Reads: "Thatcher's Dairy Bottle Patent 1884 One Quart" on the other side reads: "Absolutely Pure Milk" with a picture of a cow. The bottom reads:  "Concord China Co 1965", "Bottle made in Italy".  It has a plastic and rubber top with wired spring to seal it.  It stands approx 10.5" tall.  These are neat.  Thanks for looking!  Email with questions.  I combine shipments when I can, just let me know.
