A hauntingly beautiful vision of this Art Nouveau lady maybe representing her inner femininity.  This would look great framed to enhance the connection that you feel.

I couldn’t find any information regarding B Patella which is rather sad as his work is highly collectible.

The card was printed in one of Germany’s states prior to Unification, probably Bavaria or Prussia, and was franked in 1905. 

Size
The postcard measures 5 1/2 inches by 3 1/2 inches

Condition
In very good vintage condition.   Please see photos.
