OK AWESOME. Talk about bringing the arts to the people, Martha Street Studio, a community-based printmaking studio recently conducted their second “Under Pressure” steam roller print festival! Found on MAKE:
For the past two years Martha Street Studio has hosted ‘Under Pressure’, Winnipeg’s only Steamroller Print Festival. High school students, community groups, and artists from across Winnipeg create large linoleum carvings leading up to the festival. On the day of the festival the carvings are inked and printed with the aid of a real steamroller.
