In December 1853, #UGRR leaders #JohnJones and #JamesDBonner began advertising their new #Chicago business venture, the General Intelligence Office

Located on Dearborn Street, the GIO was an employment agency, realty office, money lender and collection agency

It most likely helped new escapees from enslavement find jobs in the City or request help from Chicago's #UndergroundRailroad

In 1854, #FrederickDouglass reprinted the ads in his own newspaper
