SOUTH PORTLAND — Some people like to spend their weekends at home lounging around in pajamas or working out at the gym in sweats, but for others there is nothing more fun than donning their favorite action hero costumes and converging on the nearest comic book convention.

This weekend hundreds of comic book fans, both costumed and not, are converging on the third Coast City Comicon, a convention at the Double Tree Hilton in South Portland devoted to comic book-related forms of popular culture. The convention, organized by Coast City Comics in Portland, features comic book artists, crafts people, music, dancing, wrestling and horror films. Many of those who attend are comics convention regulars.

“I go to as many as I can,” said Bob Tkacik, a Portland graphic artist who was selling his own art at the convention.

Tkacik said he usually manages to sell enough of his graphic illustrations to cover the cost of attending the convention.

“And I get to talk to nice people all day,” said Tkacik.

A seven-man contingent of the Maine Ghostbusters chapter was on hand in their signature army fatigues and power packs. The chapter appears at events around the state to help raise money for charitable causes, said member Justin Hamner of Rumford. Their appearance at Coast City Comicon will benefit the Center for Grieving Children, Hamner said.

Hamner owns the chapter’s Ghostbuster cruiser, complete with flashing red lights and a Maine vanity license plate, Ecto 207.

The vehicle was parked outside the convention center Saturday.

Joseph Schmalke of Portland, a master controller at WMTW-TV by day, was selling copies of his comic book creation, “The Calamitous Black Devils,” a World War II horror science-fiction series published by Broken Icon publishers.

“It’s an elite brigade of army operatives who are trying to stop Nazis from opening a multidimensional gateway to let in ancient gods into our world to raise an army of the dead,” Schmalke said.

The graphic novel featuring the elite brigade is due out soon, he said.

The convention also featured an array of traditional crafts with a comic book twist. Trent Schriefer of South Berwick was selling his medieval wasters, which are wooden replicas of metal long swords and other weapons used for practice.

“It brings back some of the ideas of honor and chivalry,” said Schriefer, who trained with a swordsmith.

Schriefer said his mini cross bow, which shoots marshmallows and retails at $25, was turning out to be a favorite.

Matthew Lambert, 11, of Hampton, N.H., who was attending the convention with his father, Ted Lambert, said there wasn’t anything he didn’t like about the event.

“I like everything,” Matthew said.

The convention continues from 11 a.m. to 6 p.m. Sunday. Admission is $25 for one day.
