Painting the New Year red ca. 1910, by H.B. Griggs

This unused postcard is signed H.B.G., indicating the artist H.B. Griggs.

Here's what I found on the web about Griggs:

Designer of more than 500 postcards who worked for the firm of Leubrie & Elkus, NYC. The subjects are often for holidays,the style is influenced by Art Nouveau, and the artist signed as HBG.
