What Dan Veltre likes about comic books is how they have readers use their imaginations going from panel to panel.
Veltre, who has owned on Park Avenue in Madison going on 21 years, discovered his love for comics after getting his first free comic book as a kid and sees his participation in Free Comic Book Day as a way to pass on his love for the medium, he said.
On Saturday, Dewey's took part in Free Comic Book Day, an annual event started in 2002 that invites thousands of independent shops to give away free comic books.
The line to get into Dewey's wrapped around the corner at the 10 a.m. start of the event and artists from the Joe Kubert Comic Art School made sketches outside for those who attended.
Attendees could choose from a selection of more than a dozen free comics, including Donald Duck, The Avengers, Spider-Man and Buffy the Vampire Slayer.
"Fifty years ago, I got my first free comic book," Veltre said. "That's how I became a fan."
