1 Answer 1


So this seems a little too easy, but I think the answer is:

Winnie Harlow, 10 June 2018, Canadian Grand Prix in Montreal, Quebec, Canada

The reasoning:

The columns of the flag are encoded with Baudot-Murray ITA2 code, and read "TWO MORE LAPS". The Canadian Grand Prix in 2018 was terminated two laps early when the race officials lost count of the number of laps.

    $\begingroup$ You got the checkmark. Yeah I figured this puzzle would be easier than most of the other puzzles in this series. At least it didn't get solved within ten minutes from posting :) $\endgroup$ May 30, 2020 at 17:23
