This is a photograph of artists in Paris (c.1890s?) from Vineland Historical & Antiquarian Society.  It may depict artists known to Richard Landis, son of Charles Landis who founded Vineland, New Jersey.  Help identifying the artists would be welcome.

The man at the left looks somewhat like Henri Matisse.  Could it be Paul Serusier at the far right?  Or how about the Nabis and friends?  Here's a photo of Ker-Xavier Roussel, Edouard Vuillard, Romain Coolus, and Felix Vallotton:
