A founding member of Kaisahan the group of Social-Realist painters that " flourished " and gained renown during the Martial Law years. A Thirteen Artists Awardee, Habulan had several solo exhibitions to his name. His solo show at the Hiraya Gallery in the early 1980s, where he displayed his signature work "Kagampan" was notable - it was a critical and commercial success and earned him his niche as one of the stalwarts of the Social Realist School in the Philippines. Gathered in that show were Habulan's now iconic images of farm workers, industrial laborers with their machines or tools of production, and people who earned their living in the streets, like the itinerant peddlers.
Habulan had exhibited extensively abroad, most recently in Singapore, where he exhibited mixed-media assemblages, among others, that reveals his long-time fasciantion with the material manifestation of fold beliefs and religion hereabouts. The title of that show - which was actually a collaborative exhibit with Alfredo Esquillo - was " Semblance/Presence ". For the present show, Habulan cut out images from his old drawings which he afterwards arranged in layers within frames. The resulting pieces, which are also assemblages really, are novel and stunning.
This series of exhibitions to assert the significance of paper in art making was Habulan's brainchild. This shows his single-minded approach in promoting whatever his advocacy is at the moment. That is integrity - and that coupled with his prodigious artistic talent are the reasons perhaps for his status as a most sought after artist here and in Singapore.
