Purchased at an estate sale, this is a very old clear depression glass baby bottle with nipple and lid or cap/cover made by Hazel Atlas. The Bottle measures approx 7" tall with lid on X 2.25" across bottom. The bottle has no marking except the maker mark on the bottom and the # 7-K-679. The lid or cap has ounce measurements of 1/2 oz, 1 oz, 1-1/2 oz, 2 oz, and 2-1/2 oz and on other side of cap it says HYGEIA STERI-SEAL. As you can see in the pictures t is something inside the bottle, not sure what it is, purhaps just paper and is free moving. I did not want to take the nipple off the bottle as it is very weatd and hard and I was afraid I could damage it. On the nipple it says HYGEIA (t is a melt make under this) MADE IN USA, PAT DEC 5 1916. T are no chips or cracks.
