Mel Bochner's "Primer" is a portfolio of twenty-one demonstrations documenting conceptual approaches to sculpture through photographs, drawings, and text produced between 1969 and 1972. Published by Gallery 360º in Tokyo in 1995, this signed and numbered edition (15 of 50) exemplifies Bochner's systematic investigation of how language, measurement, and spatial relationships constitute sculptural meaning rather than traditional material form. The work reflects the artist's pivotal role in Conceptual Art's theorization of sculpture as an intellectual and linguistic practice.
