Part of Holzer's powerful "Water Boarding" series, this 2012 work exemplifies the artist's decades-long investigation into the intersection of language, power, and political transparency. Measuring 90.424 × 70.104 cm, the piece continues Holzer's practice of appropriating and recontextualizing official documents to expose hidden governmental operations. Acquired from MLTPL, "Top Secret 23" demonstrates the artist's unflinching commitment to making visible what institutions seek to conceal through redaction and classification.
