Aragon started his career at the Daily Express. He was a professional cartoonist in Manila in late 70’s, working at Nonoy Marcelo’s studios as artist and animator. At that time, he was also a contributing strip and editorial cartoonist at The Philippine Bulletin Today and Philippine Daily Express.

He left for Australia with (late) wife Virginia in 1979 and made a career as opinion-editorial page cartoonist of the Sydney Morning Herald, The Australian, and the Daily Telegraph. Aragon was awarded Artist of the Year in Australia in four different illustrative genres.

The first of his exhibits, Digitalla Prima, are digital prints consisting of 20 manipulated photographs and scanned images using paint programs. The exhibit opened recently at The Oarhouse on No. 1803 A. Mabini St., Malate, Manila, and will run until the first week of next month.

The second exhibit, Mulat, is Aragon’s "invisible" paintings on canvas of legendary musicians, nudes and allegorical images. On display at the Banyuhay ni Heber Arts & Music Center 170 on Banlat Road, Tandang Sora in QC are about 30 white canvases with images visible only under ultra-violet light. Central to the exhibit is a life-size portrait of Tandang Sora aka Melchora Aquino, Mother of Katipunan. She was born in Banilad (Banlat).

Exhibit 3 is a collection of Aragon’s opinion editorial cartoons and caricatures published in The Sydney Morning Herald, The Australian and The Daily Telegraph, including prints of his political cartoons currently on exhibit at the National Museum of Australia, Canberra.
