This is clear evidence that the Osiris decor belongs to the Ernst Steinwald & Co. glassworks. (from the German periodical Schaulade from 1931). It is also worth noting the used shapes of glass, which are known from the decors attributed to Kralik.
Decor Osiris had several variants. Certainly in addition to "vertical" also "horizontal" see: https://www.collectorsweekly.com/stories/266767-kralik--osiris?in=442-activity
Just as Flowerall and Bambus decors were produced in many variants and combinations, Osiris decor could also be combined with other decors in addition to the vertical and horizontal variants. In photo 2 from the Passau Glass Museum there is a vase, the decor of which, in my opinion, could also be a variant of the Osiris decor.
