Young patients at Children’s of Alabama were greeted by a group of superheroes in the form of window washers dressed as comic-book favorites.

According to AL.com, Sunlight Building Services LLC provided the workers through a contract with Hoar Construction LLC and sent window washers dressed as Batman, Superman, Spiderman and Captain America this week.

As they made their way down the building, the quartet stopped at each floor and engaged with the kids inside.

The display was part of an ongoing partnership between the Birmingham hospital and Books-A-Million.

A program known as The Power of Children’s has previously provided such surprises for patients and will continue with the superhero theme throughout the remainder of this month.

Patients are getting in on the dress-up, too, with children donning capes and other costumes in honor of their favorite superheroes as the window washers appeared before them.

In addition to providing the youngsters a visit to brighten their day, the program aims to provide some longer-term benefits.

The site describes this partnership as a way to “honor patients and staff as the real superheroes that they are, while bringing awareness to the importance of Children’s of Alabama throughout the state.”

Organizers of the annual program also encourage the general public to share their support.

“Members of the community can also post photos wearing superhero capes in support of the patients using the campaign hashtag,” the online announcement concluded.

The program’s website includes video from a similar event last year.
