"When I see an old image in my mind, it's typically black and white," said the 29-year-old Martino. "Even when I think of something from the 1970s, and although color photography was available, I think of black and white."
Later this month, Martino will release, "Take A Journey Back in Time With Phoenixville," which is part of the "Then and Now" series from Arcadia Publishing.
The 96-page work is composed of all black and white photographs.
Photos that date from as early as 1883 are set side by side with more recent pictures, most pairs taken from the same place and angle.
The reader is given the chance to fully realize - through a pair of images - how dozens of Phoenixville structures and landmarks have changed in appearance over time.
"There's a story to tell, although it might physially be the same structure," said the historian.
Martino spoke of lost history, and the value of many of the photos contained in the book, which have never been previously published, or not all in the same place, as they are now.
He talked about the role of the living, while preserving history.
"There are so many incarnations," said Martino. "When people died, those stories often died with them, if there's not someone to pass them along to tell those stories."
Married with no children, Matrino was born in Phoenixville and lived in the borough until he recently moved to Eagle. He has been employed in the accounting and finance field after graduating from Cabrini College.
His interest in history began as a child, when his mother gave him a couple of postcards which depicted Phoenixville.
"From there I just gradually started looking for more so I could start a collection," he said.
Martino still collects several historic photographs, including postcards, newspapers and local year books.
The 1996 Phoenixville Area High School graduate said that he often enjoys his role as a historian and displaying residents with images from the past which depict their homes or other specific buildings.
"I'm honored when referred to as a source,"said Martino.
"Take A Journey Back in Time With Phoenixville" is Martino's second book, and retails for $19.99. It will soon be available at Barnes & Noble, Border's, Amazon.com and directly from Arcadia Publishing. Seacrist's and Gateway Pharmacy may also carry the book.
