The Sang Bleu etch also appeared on Seneca's stem #484
This bird pattern is similar to Morgantown's Saranac etching pictured on page 71 of Snyder's book. A close comparison is revealing - the birds, branches, and central frame of these two etches appear to be identical. In the Morgantown version, the side torches curve inward around the frame and the lower swag is much longer.
The torches are vertical in Sang Bleu, with a floral basket or urn between them at the top of the pattern. I presume the same designer created both versions. The Sang Bleu etch also appeared on Seneca's stem #484 which is pictured at replacements.
