If you are new to collecting fine art, the price tag on an original piece like this can be a surprise! Unlike standard, mass-produced decorative prints found at home goods stores, this is a verified historical investment asset. Here is exactly why this specific piece is highly valuable to art collectors:
1. **Museum-Listed Artist:** Mariano Ortuzar is a globally celebrated 20th-century Chilean master whose original works are featured in elite private collections worldwide, including those of Pope Paul VI in the Vatican, Governor Nelson A. Rockefeller, and Mrs. Jacqueline Kennedy Onassis.
2. **100% Original Masterwork (Not a Print):** This is a true, one-of-a-kind original watercolor painted directly by the artist's hand in 1976. Every brushstroke represents unique historical value.
3. **Rock-Solid Provenance (The "Holy Grail" Paperwork):** This painting includes its original 1970s New York City studio promotional biography sheet attached to the back. Most importantly, the paperwork features a massive, bold, authentic hand-signed personal autograph by Mariano Ortuzar himself in dark fountain pen ink. Finding a verified painting paired with the artist's documented signature on the studio provenance is incredibly rare and drives up its gallery appraisal value.

**About the Artwork & Style:**
Rendered in a magnificent Tonalist, atmospheric impressionist style, this 1976 masterwork depicts a quiet body of water at dusk or dawn. Ortuzar expertly utilizes precise wet-on-wet watercolor washes with a warm, sophisticated palette of golden ochre, earthy browns, and deep forest hues to create a hazy, meditative reflection of trees across the glassy water.

* **Signature:** Hand-signed and dated "M. Ortuzar '76" in the lower right corner.
* **Document Details:** The studio sheet lists his official mid-century gallery representation and home studio address at 69 West 9th Street in Greenwich Village, New York, NY.
