another great find was this singer cardboard sign produced in Brussels around 1880 by Chromo masure in "Bruxelles rue des Alexiens 43"
with it's original tax stamps, it's missing a little part o nthe right side and top but i'm sure there are no much of those still existing
the machine depticted on the ad is from 1870 and I think the statue of Liberty is from Isaac Merritt Singer's wife Isabelle Boyer who had an affair with sculptor Frédéric Bartholdi, served as his model for the facial features of Bartholdi's most famous work, the Statue of Liberty.
the address on the bottom of the cardboard is from a shop in Liege near where I live, Liège 7 rue de la régence, sadly it's now gone and it's a bakery shop
