When the students at Marjory Stoneman Douglas return to class on Wednesday, they'll be greeted by a mosaic of hand-painted hearts from their peers in Newark, New Jersey.

Students at Ann Street School are hoping their art -- made more than 1,200 miles from South Florida -- can bring some color and comfort to Parkland school hallways after a 19-year-old gunman killed 17 students and teachers during one of the deadliest school shootings in history.

The Valentine's Day massacre has prompted an outflow of support from students and schools across the country.

Using bright reds and pinks, yellows and greens, about 150 students from Ann Street School painted hearts and murals to mail to the Parkland students.

Students at Ann Street School in Newark sent artwork to Parkland for when the students return to class.

"Having our students participate in the creating of art work for Stoneman Douglas High School in Parkland, Florida as a sign of our support the students of Parkland in the recent tragedy is admirable and empathetic," Linda Richardson, principal of Ann Street wrote to administrators.

The students made collages, used crayons and watercolors, writing "Our hearts are with you," on one of the large murals.

The artwork was mailed out on Friday and is expected to arrive in time for the students' return to school on Wednesday.

The mass shooting in Florida has moved students across the state to action. Last week, several hundred students walked out in solidarity with their Parkland peers as they demanded action on gun control.

A larger school walk-out is planned for March 14.

U.S. Sen. Robert Menendez, D-N.J., is holding a rally for common sense gun legislation on Sunday in Livingston with survivors of the Parkland shooting.
