This is a very pretty small aqua glass bottle which was molded but has an open pontil.

Lots of bubbles and waves in the glass - no dark marks - that just shows in the photos for some reason.  Very clean.

Mold likes down the sides and at the bottom

Smooth rim

Nice small size: 6 1/2" x 3" x 2"

Dating from the late 1800s and found in Massachusetts.

$10 shipping.
