The tiny doors that have been popping up all over Atlanta now have an even tinier accessory: AJCs.

The miniature newspapers are unaffiliated with Tiny Doors ATL, which debuted its first public art installation in July, the group says — and it isn't sure who's been placing them around town.

“We have a vague idea of who may be leaving the papers, and could probably find out,” said Karen Anderson, co-director of Tiny Doors ATL. “But we kind of like the mystery of it all.”

The AJC was able to trace The Tiny AJCs to a man operating under the pseudonym “Scoop Callahan."

Callahan said he considers himself a "beat reporter" for the tiny paper and proclaims to be one of Tiny Door ATL’s “tiniest fans” since discovering a tiny door at the Krog Street Tunnel late last year.

“I had no idea why it was there, but [I] decided right there and then I wanted in at the ground level and help celebrate the creativity,” he told the AJC via email.

The first edition of The Tiny AJC rolled off the presses on Nov. 15, 2014, and was delivered to the doorstep of that Krog Street installation, Callahan said. The front page story appropriately covered the whitewashing of the Krog Street Tunnel graffiti.

Callahan has since continued printed editions of The Tiny AJC, coinciding with the debut of each new tiny door.

“I thought creating The Tiny AJC would be a unique way to interact with the tiny doors while also creating a whole new canvas for sharing imagery and happenings in Atlanta,” he said.

Tiny Doors ATL has so far placed six different doors around the city, with more planned. The artist cooperative's intricately designed projects have become an interactive part of the community, and not just from Callahan.

For example, in December the cooperative installed a tiny door outside Inman Park Pet Works, complete with a tiny pet door. Not long after, someone tacked tiny fliers to the tiny door’s tiny bulletin board.

“That was the kicker for us," Anderson said, "to see people participating and making the installation their own was exactly the reaction we wanted."
