2026 Sherlock Holmes Keepsake Premiere: Conan Doyle Cut, Printed Pages and Prop Relics
The November release separates fictional-character signature designs from actual author ink.
We update this release guide as verified product details develop.

Sherlock Holmes Premiere has a genuine author-autograph chase: an Arthur Conan Doyle 1/1 cut signature. Around it, Keepsake builds a November 18, 2026 Breaker release with black-and-white and color base cards, relics from original printings and movie props, and designs featuring Holmes’s fictional cast. Manufacturer details
Twelve cards, one hit
Each box contains two six-card packs and one hit. That distinction matters in Keepsake’s Breaker lineup, where several other products offer two. The base parallel sequence includes Blue /99, Red /50, Gold /10, Green /5 and Black 1/1.
The black-and-white and color treatments give the portraits two different visual registers. They also fit a subject whose stories have been interpreted through illustrated print, film and television.
Author ink is separate from character graphics
Holmes, Watson and Moriarty receive Laser SignaGraph designs. Those are graphics for fictional characters; Conan Doyle’s cut signature is the separate original-autograph chase.
The material program includes relics from original printings and movie props. Keepsake also advertises coin-related cards, including 1/10-ounce gold and silver versions. The precise item and its attribution depend on the individual card. The release’s strongest connection to Holmes is that mixture of printed-story material, screen props and an autograph from the writer who created him.
