SINKHOLES 2025 📌 available exclusively through the Hidden City Philadelphia fundraiser @hiddencityphila This calendar consists of sinkholes, cave-ins, and other vacancies in the 20th century streetscape of Philadelphia. The sudden appearance of these chasms are a reminder that the urban world is not always as solid as it appears. The photographs were taken by various staff photographers for the Philadelphia Evening Bulletin, available courtesy of the George D. McDowell Evening Bulletin Archive at the Temple University Urban Archives. @temple_scrc Graphic design by the amazing Saskia Globig @billly_ellliot Printed at Fireball Printing @fireballprints
