In 1973, art found itself at the forefront of a cultural shift. The United States military had just pulled out of Vietnam after nearly two decades and midcentury optimism had given way to uncertainty. Art, even when created for mass appeal, took on a darker tone. 1973's highest-grossing movie - The Exorcist - and top-selling album - Pink Floyd’s The Dark Side of the Moon - gave us a glimpse into the cultural landscape of the time.The following year, a new wave of art - films like Chinatown and albums like Bob Marley’s Natty Dread - shined a light on a broken system. And gave us the tools to understand it. Art reflects the world around us and helps us process complex issues so that we can move forward. Leonard Cohen once said “There is a crack in everything. That’s how the light gets in.” Art creates cracks in the world’s darkest places, letting in the light of knowledge.Fifty years later, the Blackwing 2 acknowledges art’s role in bringing about change. Each pencil features a cracked glow-in-the-dark design that plays on the duality of art and the challenging realities that inspire it. Each pencil also includes our firmest graphite yet - a special 2X firm graphite formulated specially for this release.All Blackwing pencil products conform to ASTM D-4236.
