Small Rindskopf vase - possibly Alhambra decor (?)

This is my latest addition from the production of the Rindskopf glassworks. The vase measures 9.1 x 5.5 cm. It is made of cobalt blue glass, has a distinct matte iridescence and is decorated with etching ink. The design and decor is very similar to the ALHAMBRA decor.
