The pics are a touch on the dark side, but I believe that this is a Kralik decor. If memory serves me correctly, I have also seen an image of an example like my first image in the Passau. I am including images of another similar example from what appears to be the same period. I would place the production at around 1900 - 1910.
Later on, around 1925-30 They revived the decor in a modernized variation generally found in a glossy finish, but with a similar internal vs external color for the piece. The later versions, of which there are several color combinations and shape variations, also have the addition of applied tadpoles on the pieces. The tall bottle form piece is an example in my collection.
The blue and orange example has a strikingly similar mouth....
