Despite the large collection photos that can be found with Nativa as model I did not find any about either Nativa or Richard. Images of Nativa often appeared under the names, Helios and Miss Milado.
She is the most captured model that appears in photos connected to the name Yva Richard, like with models who posed for Biederer Studio most models who posed for Yva Richard Studio remain anonymous.
To search all galleries with Nativa as model use the search option. Enter Nativa and it will bring up all shoots for which I was certain Native was the model.
