Jan. 23 marks National Handwriting Day, an annual celebration of the power and magic of the written word. The occasion, which was launched in 2013 by the notebook company Moleskine, coincides with the birthday of John Hancock, owner of the most famous signature in history (on the Declaration of Independence, in case you've blocked fifth-grade history from your memory). To honor the day, celebrities like Bruce Willis and Debra Messing will be tweeting out handwritten notes (and illustrations, in some cases) to their followers. “I strongly believe that paper and pen are not at all destined to disappear, but rather to transform and develop," says Maria Sebregondi, co-founder of Moleskine. “The advanced technologies of today can embrace the cognitive and emotional power of the analog world, taking it to a new level." 11 Fun Office Supplies to Buy Now Share your own John Hancock on Twitter by using the hashtags #handwritingday and #moleskine, and keep scrolling to see how the others are participating. 01 of 11 Debra Messing, Actress Courtesy 02 of 11 Bruce Willis, Actor Courtesy 03 of 11 Emma Heming Willis, Model and Actress Courtesy ...And an adorable cameo by Mabel, Emma's daughter with Bruce Willis. 04 of 11 Adam Leibsohn, COO of Giphy Courtesy 05 of 11 Liza Donnelly, New Yorker Cartoonist Courtesy 06 of 11 Matthew Freedman, Author Courtesy 07 of 11 Justin Peters, Columnist Courtesy 08 of 11 Alison Bechdel, Author of Fun Home Courtesy 09 of 11 Connie Schultz, Pulitzer Prize-Winning Columnist Courtesy 10 of 11 Gabrielle Hamilton, Chef and Owner of N.Y.C.
