remarkably rare and intact c. 1840's or early 1850's antique american richly colored cobalt blue soda bottle with an open pontil manufactured for chicago bottler george lomax. this bottle is the only known example of a chicago soda bottle to contain an open-pontiled scar in the base. the front of the slim-bodied glass is embossed with the bottler's name and city inside a debossed plate with rounded corners. the long neck is finished with a somewhat crude rounded tapered collar that features visible slop, whittling and a large bubble. the base has a shallow kickup with whittling and a central scar that extends to the base edge. visible side seams run from heel to the bottom of neck. crudities in glass are typical of its age and date of manufacture. the george lomax soda bottle with applied top has been tumbled. the privy-dug bottle remains in great shape, considering age.
