Unusual suggestion Raimond. I'll keep that in mind.
or we may rely on the Stanley Gibbons describer:
"various girls wearing different provincial cotumes"
I would think somewhere there is a discourse on these
delightful sets by J Seger somewhere on Austrian bookshelves.
...and found it

When it was decided in the middle of 1948 to introduce a new definitive set of stamps, it was necessary to select a topic which would be not only of general appeal but also representative of the whole of Austria. The final decision was to use an idea which had proved very popular in 1934-36, namely to use the traditional costumes of Austria as the theme. Professor Josef Seger (b.1908), a pupil of Alfred Cossmann, who had studied at the Graphical Teaching and Research Institute in Vienna and then at the Academy of Pictorial Art, was selected as the designer of this set. The Museum of Folk Art in Vienna did the original research for the costumes. It had long been believed that one of his girl students, whose likeness is most apparent on the 50g stamp, posed for Professor Seger's drawings; but it is now known that there was no model, the designs being a purely intellectual creation.
