A recent Bonhams Auction 13 December 2013
Lot 10 shows this becher with dog and vines. It is dated 1866.http://www.bonhams.com/auctions/21673/lot/10/
It is blue over clear only, not three layer, and attributed to Karl Pfohl.
In the description there is reference to the 'scroll work' and that one with 'closely related scrollwork' is in the Passauer attributed to Karl Pfohl. The scrollwork looks like the work on my vase.
No three layer cameo pieces in the sale though despite 10 of these two layer pieces.
The description reads:'A Bohemian cameo beaker attributed to Karl Pfohl, Steinschönau, dated 1866
Overlaid in cobalt blue, of campana shape on a spreading foot cut with ovals and trefoils, cut and engraved in shallow cameo with a dog standing on the forked branches of foliate scrollwork, a lens on the reverse engraved with the date 6/2/1866, 16.8cm high
A tall goblet with cameo work including closely related scrollwork attributed to Karl Pfohl, is in the Passauer Glasmuseum, illustrated by Georg Höltl, Das Böhmische Glas 1700-1950, vol.3 Historismus, p.68, fig.76. Other similar pieces have been attributed to Franz Zach, including a goblet in the Rinceaux Collection, Sotheby's 18 December 2001, lot 160
Another that is just interesting to look at - dated 1850-1860 and detailed cameo work
