Hi everyone I’m new to the site. Also new to bottle collecting though I’ve been an avid Seaglass collector. The summer in Massachusetts I was hunting Seaglass in a harbor and I figured out where that was coming from as I located a amazing cache of bottle's and pottery . It dates from the 1850s to probably the 1920s-40’s not really sure. Rich people’s town on water. Couldn’t find any information on the oval jar. Could be cosmetics. I found two.
