Duraglas brown swirl bottle made by Owens-Illinois Glass Co in 1942. Marked by the Diamond O-I mark. Stippled bottom was first used in 1940. Also has the Duraglas mark around the side near the bottom and seams on the sides. Measures 11" high. It is in excellent condition with no chips or cracks. Great for general display, for holding coins, or for turning into a lamp as many people did in the 50s. The third photo shows the actual markings on the bottom of this bottle.
