I found this old carboard display this morning in a flea market
my eyes were catch by the colors who were really great and the graphism, but when I saw the small text line at the bottom " Sinclair petroleum company S.A. ", I know I have to buy it.
the sign is in really good condition, single sided with a tax stamp on it (it was a tax paid to advertise here in belgium used until mid 1990) the stamp is oblitered with this text : sinclair petroleum - 28 oct. 1931 - company S.A.
was it common to petroleum company to produce and sell insecticide sprayer ? Did others company produced thos sprayers ?
here are pics of the sign :
