2 old bistro glasses, flared, in blown glass

These blown glass glasses, with flared necks, are rare! I had never seen any with this shape. They are probably older than the usual "coffee" glasses: it is in these glasses that coffee was served in country bistros. These have a thinner rim than the usual classics. Nb one of the 2 glasses has a small lack under the foot, it can be seen in the photos, it is not much.
