The challenge to sketch one hundred people in five days is the brainchild of artists Marc Taro Holmes and Liz Steel, who jumpstarted the initiative seven years ago. During this week, thousands of amateur and pro artists worldwide line up beside them to sketch people, live or from reference photos. It doesn’t matter, as long as you keep the stream going, putting out as many sketches of people as you can, and posting them online to share with the wider community.

oris Johnson is the current prime minister of the UK. His wacky demeanor might conceal a Machiavellian intelligence. No matter if planned or improvised, his tactics of wit and confusion appear to be the political weapons of choice of the current era.

Sheldon Cooper is the socially inept physics genius protagonist of the TV sitcom The Big Bang Theory. His rare moments of emotion are frequently of anger and frustration at a world that simply does not obey his optimal solutions.

Salgueiro Maia, a key player and a Carnation Revolution hero for many, led a mechanised cavalry column into Lisboa, aimed at taking key targets and capturing the government members. His role in the negotiations was critical for the peaceful outcome of the Revolution.

Corto Maltese is the last of the romantic soldiers of fortune. The mythical character, authored by Hugo Pratt, stands on the edge of ancient traditions and modern history. Pandora Groovesnore is the future… and his impossible love.

Remember the Japanese folding sketchbook from last year? I filled one side of it with a crowd! I’m planning to finally fill the blank side, and I’m keeping my promise to Carla Silveira and Celeste Vaz Ferreira, who, one year ago, suggested on instagram that I should do one hundred hands next. Thanks for the idea girls!

Last week, Liz Steel and Marc Taro Holmes challenged sketchers worldwide to spend a workweek sketching one hundred people.

Thousands of people took the challenge worldwide. Liz and Marc can be proud that they made the world sketch quickly and loosely for a single week.
