One of Haulers latest diorama accessories is a 1/72nd scale poster column. (They also offer a 1/48th scale poster column.) These advertising columns were ubiquitous throughout Europe during the early portion of the twentieth century. In many cases a version of these poster/advertising columns can still be seen in Poland, Germany, France and elsewhere.
I haven't located any definitive evidence but it appears as if Hauler may have inherited this kit from Tiger Productions. Scalemates website currently lists this kit as having been issued by Tiger productions in 2011. Tiger Productions may have been affiliated with Black Dog (https://blackdog-model.com/), a maker of resin structures and diorama accessories. All of which is speculation but it makes sense in my head.
