Trio of Loetz Phänomen Genre 6893 Vases in Consecutive PNs

As indicated on Loetz.com, Phänomen Genre 6893 was one of the earliest of the Phänomens, and it was executed in just about every ground color that Loetz made. Here is a special collection of this decor in three different colors, and on three consecutive shapes, dating to 1898 - I/7572, I/7573, and I/7574. The ground colors are (L to R in the last photo) mountain blue, metallic violet, and opaline.
