Does anyone know anything about Taber Prang art? I have a print that appears to have hand coloring on it and, on the bottom right, there is an upside down triangle with 19 on one side and 09 on the other. Below that, in whitish gray, it says "copyright 1913". Below that is says Taber Prang Art Co.

It appears to be printed on cardboard type paper. It's beautiful with subtle colors. And there is definitely hand coloring. I can't tell if it's a lithograph or what but, to me, it appears to be done with the dry point method.

I don't know much about prints but trying to figure it out.

Any ideas?
