Photo: Dr. Pio Valenzuela with historians (1950s)

1950s. Kuha sa bahay ni Dr. Pio Valenzuela sa Pariancillo Villa, Polo, Bulacan.  Ayon kay Dr. Casambre, anak ni Prof. Gabriel Fabella ang dalawang babae. Ang nasa gitna ay si Dr. Pio Valenzuela. Ang binatang lalaki sa gitna ay si Dr. Napoleon Casambre, nasa kaliwa niya si Propesor Fabella at nasa kanan naman niya si Prop. Serrano ng UP. Galing ang larawan kay Dr. Kristoffer Esquejo ng UP.

Mula kay Dr. Napoleon Casambre (nasa gitna ng larawan sa likod ni Dr. Pio Valenzuela na nakaupo; comment niya sa ito sa Facebook, 2015):

"Yes, I was already with the History Department when the photo was taken. Prof. Fabella was not the head of the Department; but was the Director of UP Extension in Clark Air Base. The head of the Department then was Prof. Nicholas Zafra who retired in 1959./ If I recall, when the PHA visited Dr. Pio Valenzuela at that time, it was to greet him on his birthday and to interview him on his role in the KKK. Prof. Fabella and Prof. Serrano (the guy on my right and lecturer in the History Department), asked him specifically about his trip to Dapitan to see Dr. Jose Rizal. His answer was and still is found in his published memoir. Even at that age when we visited him, he still had a vivid recollection of the KKK and its role in the Philippine Revolution. And it amazed me no end!/
