This 1966-1969 produced bowls with blue Corning Ware Stamp was purchased at an estate sale. I do have other bowls listed with this stamp also. As stated these bowls are in Very Good VTG condition see all photos of imperfections. I will label each bowl and lid separately as #1 (pictures taken in chair) and bowl and lid #2(taken on blue spread).The VTG glass lids with this much age do tend to show slight usage naturally. See all photos for best description. Referenced Corning Ware 411 blogs and Rarest.org for values etc. Alaska and Hawaii residents are responsible for the additional shipping. International buyer is responsible for import fees, etc.
