Roberto Chabet's Book of Scraps and Scratches in the group exhibition 'Collage' curated by Ray Albano at the Cultural Center of the Philippines (CCP) Small Gallery from 23 July to 8 August 1976. 

Excerpt from the exhibition notes:
'Roberto Chabet has accomplished a body of collage works in the 1960's, many of which were in black-and-white monochromes. In his black-and-whites are seen optical rhythms of hard-cut markings, while in his chromatic ones he succeeded in making hard-edged surfaces ambivalent. At present his collages are done in loose systems and incorporating a great deal of drawing.

In his new collages, Chabet expostulates on a new content by selecting readable collage materials and chance-relating them with the artistic process.'
