A Sala postcards used several logos but all apparently include "ASB". The cards with the logo containing a tree include a lot of figurative cards for the US market from around 1908; embossed cards with colourful rather crudely drawn figures, some with American patriotic themes. These have been widely ascribed by dealers and others (eg the Museum of Fine Arts Boston) to Arthur Schürer & Co. However the TPA article has identified them as by A Sala.
The second example card has a series of doors which can be opened to see what is happening inside.
