Rare Pink Richard/Loetz Landscape Cameo

From the dealer's description: "It features an acid etched (frosted) pink over white glass, with a forest scene and a cottage by the maker's signature. A very unusual color for this fine maker. The vase measures 8" tall, and 3.25" wide. " The dealer placed it around c.1920; I think it is quite later. I had never seen a Richard with an "optic" pattern before, or a Landscape in pink glass, and the mark varies a bit from other Richard marks. No pontil. But Pic. 4 reveals the real reason I got it: to match with a 9.5" Landscape in blue-green over white. I do not have PN's for either.
