Letter from Elvira Manahan to Joy Dayrit, dated 6 September 1969.

In this letter, Manahan expressed her gratitude to Dayrit for arranging the guest appearance of Ramon Katigbak and Benjamin Bautista, who showed the paintings of Angel Flores on her television talk show, 'Two For The Road,' which aired on ABS-CBN Channel 3 on 1 September 1969.

Angel Flores (1936 - 1968) is a Filipino expatriate artist who died in a motorcycle accident in the US, leaving behind an English girlfriend named Sheila Hollister and around twenty paintings, which Sheila turned over to his two former Ateneo High School classmates, Ramon Katigbak and Benjamin Bautista, in 1969. Some of Flores' paintings were included in 'Summer Exhibition' at Cultural Center of the Philippines (CCP) in 1970 and in the survey, 'A Decade of Developmental Art,' also at the CCP, in 1979. A solo exhibition was also mounted at Joy Dayrit's Print Gallery in 1971.

One of the surviving panels of Angel Flores' four-paneled acrylic on canvas with zippers painting, Three Paintings and One Drawing. The four-paneled painting includes three acrylic paintings with zippers, in violet, orange, and pink, and a blank canvas.
The work is part of a series of zipper paintings created by the artist around 1965, when he was living in New York. It refers to the slashed paintings of artist Lucio Fontana.
The work was included in 'Summer Exhibition' at Cultural Center of the Philippines (CCP), curated by Roberto Chabet in 1970, and in the survey curated by Ray Albano, 'A Decade of Developmental Art,' also at the CCP, in 1979.

He was an fictional persona co-created by Benjamin Bautista, Ramon Katigbak, and 'Angel Flores Jr.' — Roberto Chabet — who produced all the artworks.
