The late design icon Massimo Vignelli, who died last year, will always be remembered for his visually powerful and timeless graphic art. To honor his memory, the Spanish design studio Husmee Estudio Graphique asked a diverse group of international graphic artists to create posters commemorating Vignelli’s life and work. The result is a wonderful show appropriately called Timeless, which will be on display through August in Barcelona and online here.
