His 1962-63 Pillows and Pillow Drawings, exhibited first at the Contemporary Arts Museum, Houston, are distinguished by the intense engagement of the hand: cutting, adding, sewing, stuffing, drawing, layering, and combining materials in ways that clearly predict his constant practice with drawings and collages through the following decades. The subsequent role of works on paper in forming Antonakos's development cannot be over-emphasized; he drew almost every day. The physicality of these compositions and of the cuts and tears and layering in his collages through the years, make them not images, but objects. The same holds for the many Travel Collages produced from the late 1970s through 2001.
