August 25, 1938: "The Mt. Penn tower. Councilman Howard McDonough said yesterday, will be striking in appearance and will compare favorably with scenic towers and observatories in other cities which cost much more than the proposed shaft here. It will be 125 feet high, much taller than the Mt. Penn Pagoda, which is about 75 feet. It will stand on a summit 270 feet higher than the Pagoda base, and probably will be surmounted by a signal light, or beacon. To be constructed ob rough native stone found on the mountain top, set in rough-troweled cement, the tower will be about 22 feet wide at its square base and 13 feet at the top. There will be two sightseers' balconies near the top and a third on the top, reached by a steel interior stairway." (Reading Times)

Penn was credited this afternoon with preventing a woman from committing suicide on the parking lot adjacent to the tower. The woman was observed running a hose from the exhaust of her car through a window and then she stuffed the windows with pillows and blankets. The fire spotter, also a woman, immediately called the desk sergeant at City Hall and he dispatched Patrolman Harry Heiser and the Reading ambulance about 2 o'clock. The fire spotter told reporter that the woman did not appear seriously ill and walked to the ambulance." (Reading Eagle)
