It was a miniature Gotham City at the Morgan Memorial Library on Wednesday as kids celebrated Batman Day.

The day of celebrating all things Dark Knight, declared by DC Entertainment to celebrate the superhero’s 75th birthday, saw more than 60 children at the library making their own Batman masks and creating their own comic books.

“It’s been a lot of fun,” said Kristen Marshall, support services manager at the Morgan Memorial Library.

Each young sidekick received a goodie bag full of posters, bookmarks, masks, buttons, temporary tattoos and activity sheets. Those who came in costume received a special prize left over from previous summer reading programs.

“We’ve been very liberal on costume,” Marshall said. “If they make a mask and put it on, that’s a costume.”

Each child also got to choose a comic book, donated by Local Heroes Comics in Norfolk, Marshall said.

Comics are an important genre, particularly for reluctant readers, Marshall said.

“For boys, there’s a lot more action going on,” she said, also noting the smaller bits of text and the illustrations that help readers follow along with the story. “It can help build their confidence for longer books.”

Library assistant Cory Bland led about a dozen children in creating their own mini-comic in a 2 p.m. workshop that he serendipitously planned before knowing about Batman Day.

“It’s good for kids to get some time to be creative,” he said. “It’s a good outlet.”

The kids folded and cut a large sheet of paper into booklets and created their comics on the individual pages. Those who needed help coming up with a storyline used “story cubes” — dice with illustrations of items, actions and characters instead of dots — to help form their comic.

Timothy Walker Jr. needed no help figuring out the topic of his story, however.

“It’s about a little battle droid walking out and he finds a clone and they have a big war,” Timothy said.
