The free exhibit is set to run through the end of May and is open from 9 a.m. to 4 p.m. on weekdays.
The artwork on display shows Holden's passion for the Baltimore Colts, his hometown, rural life and the Amish, among other subjects. His photographs also feature celebrities such as Willie Nelson, Waylon Jennings and Robert Redford and local folks like members of the Panos family, who ran the old Candy Kitchen in downtown Bel Air.
The exhibit also includes Holden's iconic 1968 photograph of a Maryland state trooper hamming it up for the photographer while standing in a reviewing line. That photograph was published in Life magazine.
Holden worked as a reporter and photographer for The Aegis from 1966 to 1972. He is the former owner of Holden Studios and Photography and other Phenomena in Bel Air. He was also a photographer for the Colts during their Baltimore heyday.
Holden was named a Harford Living Treasure earlier this year and honored by the county council.
He contributed an article to The Aegis last month about a clean up of the Scott Creek Valley near the old Wye Trestle of the Maryland and Pennsylvania Railroad.
In February, the newspaper published many of Holden's photographs he shot 40 years ago while covering what has become known as the Great Bel Air Fire.
Earlier this year, Holden's work was also featured at the Lowe House Office Building in Annapolis. It was displayed there until mid-April.
"I felt at this stage of my life, a retrospective exhibit of my black and white images was in order," Holden wrote in an e-mail. "It seemed the horse was the unifying thread for this project."
He noted the Colts, the Amish horse auction at Bart, Pa., and the National Bohemian team of horses touring East Baltimore/Fells Point.
"These images were dormant for many years, and my son, Sam Holden, an accomplished photographer himself, came to the front and helped in the selection of the images that he hand printed, 'old school darkroom' analog method," Holden said, explaining he had developed the negatives himself in a darkroom over the years.
"It's totally 'old school' and I still think it produces the best images of my work," he wrote.
