There's a more complicated conversation to be had re: the meaning behind "heritage" marketing. We're mostly very comfortable with it in the USA, because to most people retro Americana = positive vibes man. But obviously the past was not a better time for everybody, and the desire for a simpler/better time is naive and sometimes dangerous. Likewise the domestic manufacturing movement in the US; the current iteration sees itself as an appeal to quality and maybe fair wages, but it can also be code for less friendly sentiments.
Germany is obviously an especially complicated case study... that postcard seems to set Leder's name in fraktur, a typeface eventually outlawed by the nazis, fwiw
