Kofi, a Ghanaian who worked as a "hype man" for video centers as a child, started collecting and selling posters.
Chankin, then a video rental store owner in Chicago, became a customer and later a business partner.
The gallery works with 15 artists, including Heavy J, who has painted posters for four decades. They connect artists to online customers and ship completed artwork.
Most orders come from the US, Kofi said.
Old action, science fiction, and horror films are in highest demand, with popular titles like The Exorcist, Star Wars, and Terminator.
Commissioned pieces start at $600.
Kofi, based in Accra, acts as manager and editor. He selects artists for each job, shares his vision, and visits their workspaces to review progress.

The Art of Visualizing the Invisible
In a studio in Ashaiman, artist Stoger worked on two commissions: one for the horror film Poltergeist, and another for the 1997 experimental drama Gummo, which features violence against cats and a character eating spaghetti in a bathtub.
His poster showed three cats and a man in a bath with a plate of spaghetti.
During a review, Kofi told Stoger that two cats were not aggressive enough and the food looked too clean.
"I want uglier cat scenes," Kofi said. "The spaghetti has to be dirtier."
Stoger, born Benjamin Amartey, was a sculptor before becoming a poster painter in 1992.
"I use my imagination to make scenes that will attract people so that they'll love the poster," he said.
