This sticker comes from CasaPound Italia's (House of [Ezra] Pound Italy, CPI) Piemonte (Piedmont) chapter, which is located in northern Italy. Although the sticker was likely produced in Piedmont, it was collected from a metal pole just outside of CPI's illegally-occupied Roman headquarters on Via Napoleone III, where the neo-fascist organization's leadership has been squatting since December 2003.
The sticker was likely placed there by CPI members who had come to Rome to attend one of the group's social gatherings or sponsored lectures at the Esquilino squat. Between 2018 and the following year, CPI hosted a number of social gatherings or sponsored lectures at their Via Napoleone III headquarters, including a roundtable discussion on the "magical archeology" of the interwar Italian archeologist, Giacomo Boni.
