These bottles were a gift to WWW.TheSCUBAmuseum.com from Gayle Peterson of Illinois. The round bottom Ginger Ale bottle is from the 1860s or earlier and is called a "round bottom blob top." It is round on the bottom to keep the cork wet during shipment. The bottles when full were transported on their sides in crates. The term "blob" refers to the the hand blowing process used to make these bottles. The other bottle is also hand blown and if you look closely you can see the bubbles in the glass. It would have had a paper label on it which has long since disappeared. This bottle dates from the late 1800s or early 1900s. Both of these bottles were found by Gayle in 1972 diving in Lake Geneva. These are by far some of the coolest bottles ever! Thanks Gayle!
