When it was drawn

What this page states · not a verdict

Drawn in 917 strokes over 00:20:45, across 21 sittings. Whether external images were imported is not checked in this record (v0). The record alone allows it to be replayed from the beginning.

View habits

While drawing, the canvas was rotated 1 times, zoomed in 13 and out 7 times — traces of working at comfortable angles and scales, recorded as part of the working habit.

Forgery difficultyVery high87/100top 34% hardest to fake

To forge this process exactly, one would have to reproduce the pressure, timing, and tremor of all 917 strokes — one by one. This isn't a verdict; it reflects how dense the recorded signals are.
