The scene
Poster Workshop · Drying tableA black line appeared across a poster’s title. Three people had visited the worktable. Only one drew the line.
A strip of blue tape stuck to the poster reveals what happened first. You only need to examine the crossing point, not estimate the ink’s age.
What we know for certain
One of these people drew the black line during their visit, without help. The blue tape was applied once and never lifted or moved. The visits and the order of the materials are verified. Nobody acted remotely.
The three accounts
Gina Soler
Illustrator«I worked in the morning and did not return.»
Héctor Valls
Installer«I stopped by late in the afternoon.»
Íria Cano
Lettering artist«I left before the tape was applied.»

01The crossing point
The black line continues unbroken across the surface of the blue tape. There is no black line underneath the tape.
02The physical rule
On this poster, a mark made before the tape was applied would be covered by it; one made afterwards can be on top.
03The reference tape
The supervisor applied the tape at 16:00. The recording confirms that the supervisor wrote nothing on the poster.
04The early visits
Gina was there from 10:00 to 10:15. Íria was there from 15:00 to 15:15. Both left without returning.
05The final visit
Héctor was there from 17:00 to 17:15. He was the only one of these three people to approach the poster after the tape was applied.
