Sentinel by Adam Dadswell.

A modern, practical approach to the drawing duplication SENTINEL is a contemporary solution to one of mentalism’s most powerful plots: the drawing duplication. At its core, SENTINEL creates clear, motivated conditions – without awkward handling, suspicious movements, or procedural clutter. The drawing is placed face down in the middle of the other billets, and that’s exactly where it stays. No displacements. No unnecessary moves. No reliance on difficult sleight of hand. Designed for clarity, fairness, and real-world performance, SENTINEL allows you to access information at precisely the right moment – under relaxed, natural conditions that feel justified and unforced. SENTINEL is ideally suited to drawing duplications and visual thought-reading, offering a calm, confident approach you can rely on whether you’re working casually or professionally.
