This is to introduce the essay discussed in my article “Thinking Straight: Queer Imaging in Lino Brocka’s Maynila (1975),” which came out in the August 2012 issue (volume 9, number 2) of Plaridel: A Philippine Journal of Communication, Media, and Society. Written by the late Ave Perez Jacob, the essay, titled “A Brief on Sa mga Kuko ng Liwanag (or Why Maynila Should Ever Be Masculine),” was published in the December 1975 issue (volume 48, number 1) of The Literary Apprentice, the official publication of the University of the Philippines Writers Club. It appears with the permission of the issue’s editorial board, comprising Professor Delfin L. Tolentino, Jr. and Messrs. Herminio S. Beltran, Jr. and P.T. Martin. Many thanks to Theo Pie for sourcing the essay, and to Vince Cuizon for photographing the pages.
