A friendly anonymous commenter, who sounds like s/he is involved somehow, offered this explanation for the new mural at the entrance to the 191st Street 1 train station:
"The mural is being sponsored by the NYC Department of Transportation and the Mayor's Office and fabricated by Groundswell Community Mural Project with Lead Artist Belle Benfield, Assistant Artist Chris Brown, and 15 teens, many of whom live and attend school in the Washington Heights area. The Y of Washington Heights/Inwood has also played a significant role in supporting the project by providing space to the team to brainstorm and design the mural. Look forward to the entire tunnel being painted this upcoming Wednesday, August 20th by City Year and 150 volunteers."
The mural project website lists Friday, August 22 - time TBA - as the dedication day for the artwork. I really hope that the artistic designs shame the taggers from leaving their mark on, at least, the mural portion of the new paint job.
