Nice pieces. Really like the becher, looks a bit special! I wonder who the chap on the panel is, what he’s doing and what’s in the bag. Looks like he’s waiting for the bus

I have the book Glasgravuren des Biedermeier, Paul von Lichtenberg (it was really cheap

). Page 95 shows a Knollenfußbecher (lump/tuber foot tumbler) that is almost identical in form to your glass Legsy. It has the same design on the sides of the cross made of three parallel lines, and the two parallel cuts just below the rim. The panels have the same eye looking design. It has four eye type panels and two plain panels that have been engraved rather than enamelled. There is no bottom view but there are six lump/tuber feet and I think it says there is a star on the bottom. From the side photo, it looks like the star is made from pairs of parallel cuts.
The photo is black and white and the glass looks clear but it is described as “Entfärbtes glas” - discoloured glass [Google translate]. Says glass and cutting is c.1835/38 Harrachsche Hütte, Neuwelt. Engraved by Dominik Biemann, Franzensbad.
