Spending a few minutes looking into this item sent me down an entertaining rabbit hole. As to crashryan's question about the "legal language" stuff, it appears that in 1949/50 the Postmaster of Chicago (Standard O & B's location) returned catalog orders to sender marked "fraudulent" rather than delivering the orders to the company. It seems the owner of Standard O&B ran numerous similar businesses as well. Said owner sued the Postmaster over this, but the suit failed and the govt proved to the satisfaction of the court that several items involved were fraudulent under postal regulations. At a glance, it appears that such rules were bolstered during the WW1 era, as Postmasters were given greater regulatory authority (most notably, at this time, cartoonists and staff of a socialist mag called The Masses were blocked from mailing it by the Postmaster and ultimately put on trial under the Espionage Act).
