Similarly to the other set of photos from Central Luzon, these were taken likely in the late 50’s or the very early 60’s. But definitely after 1956 as the Laguna Trans. Co., Inc. was called the Laguna Trans. Co. before 1956 (https://lawphil.net/judjuris/juri1968/apr1968/gr_l-23266_1968.html_)
and before 1962 as the long hair of the later 60’s had yet to make their appearance.
