Lennie Mariano is a Navajo silversmith documented in Hougart 5e for stamp work with some coral stones. The entry is brief, carrying no birth year, active period dates, or award history — consistent with a working silversmith known primarily through the secondary market rather than through gallery exhibitions or institutional recognition.

The mark

Per Hougart: Mark M. A single-letter M stamp is among the least diagnostic marks in Navajo silversmithing, shared by a large number of silversmiths. Attribution of pieces marked only "M" to Lennie Mariano specifically requires additional provenance evidence (style corroboration, dealer receipts, or accompanied documentation).

What is known

  • Nation: Navajo
  • Techniques: stamp work; some coral stone sets
  • Mark: M (single letter; low diagnostic value without provenance)
  • Adjacent in Hougart: Henry Mariano (H M mark)
