An Idaho family has found more than 1,600 vintage baseball cards from the 70s and 80s stuck on a hidden wall inside the home they were renovating.

Melissa Brodt discovered the wall covered in asphalt roof shingles while renovating a Boise home for her son Luke. She pulled apart the material and was greeted by a treasure trove of baseball cards stuck on the wall underneath. A few of them apparently had legendary figures like baseball players Mike Schmidt and George Brett and manager Whitey Herzog.

"We're not really baseball fans so I didn't really know what I was looking at, but lots of friends said, 'Oh, I know that guy,'" Brodt told CNN.

Unfortunately, the cards may have already lost their value due to being stuck on a wall for a long time. Brodt's son attempted to remove a few of them, but their pictures just tore away from their cardboard backing.

"The only way to really remove it is to cut the drywall out and take it in pieces," Brodt told the outlet.

The house was built in 1969 and the family of its original owners still live in the city. Brodt reached out to them after making the discovery.

Chris Nelson, 44, the son of the house's original owner, said he remembered decorating the wall as a preteen living with his family. He added that his artistic mother let him jazz up the room every couple of years, according to the New York Daily News.

"In the late 80s, I was absolutely obsessed with baseball. We just decided we were going to wallpaper one of the walls with the excess baseball cards," Nelson said, as per CNN.

"We got some pretty strong adhesive and each of us got a stack of cards and a brush, and we would just paint the glue on the back and tack them up on the wall. It was a nice little family activity," he said further.

When the Nelson family decided to renovate the room, they covered it with shingles as the cards were hard to remove.

"We ended up with a few packages of roof shingles, and we just nailed them up on the wall and painted them," Nelson recalled.

Brodt has no interest in preserving the wall, but she'd love it if somebody who finds it useful would take it.

As for Nelson, he does not care if the wall will be preserved or not. What matters is it brought back good memories of his parents, who both passed away last year.
