PS 139 has been a part of CHALK4PEACE in Lodz, Poland since 2007, honoring John Lennon’s birthday in October no matter how chilly it is!!! Anna and Arek Tomasik and Aneta Grzelak have been organizing and documenting these CHALKSTAR's messages of Peace for more than 10 years! Thank you to all who participate! We think John would really like what they do! Kreda dla Pokoju!
