"The Helpful Art in Covid project and exhibition was created thanks to a face mask we created on the Lennon Wall in Prague in the spring of 2020, during the first wave of the Covid-19 pandemic. We all had to put on a face mask. So we symbolically placed it on the portrait of John Lennon on the wall, which has been a symbol of freedom and love for our country for decades. Photographs of Lennon's wall with a veil have traveled the world and been published in hundreds of media. ”Says artist Pavel Šťastný, author of the project and exhibition.
