GUEST: I brought some Pearl Jam posters.

They were a gift from a friend that was in the rock and roll industry.

He said they are some of the first Pearl Jam concert tour posters ever created.

He, uh, was on tour with them.

They were given to him by the brother of Pearl Jam's bass player.

And apparently the brother was the one who produced all the posters.

APPRAISER: How long ago did he give them to you?

GUEST: Within the past ten years.

This poster was for the Prague November 15, 1996 concert.

And apparently they got into town, there was a massive snowstorm.

They were two hours late.

They threw everything up onto the stage and they just started playing.

Eddie Vedder climbed up on the scaffolding of the lighting and sat up there and sang the last song.

APPRAISER: Oh, I'm trying to envision this in my head.

This is awesome!

There are not enough words to describe-- I feel I can't even do it proper justice, of how important Pearl Jam is when it comes to '90s rock, alternative rock.

I mean, that Seattle sound, grunge music.

They were part of the taste makers at the forefront of this movement.

They formed in 1990.

1991, their debut album, Ten, I mean, that just shot them into the stratosphere.

And you are correct that these are some of the earlier concert posters for Pearl Jam.

What in the trade today, collectors call gig posters.

They weren't meant to survive.

I mean, they, you know, hang up in a college dorm, they'd be in a bar, they're meant to be tacked up... GUEST: Yeah.

APPRAISER: ...rip 'em down, the show's over.

They were all by the Ames Brothers.

Coby Schultz and Barry Ament.

With the silk-screening process and how these were made, they're highly limited.

They were printed in small batches.

And when you just look at the quality of the artwork, even outside of the connection to Pearl Jam, the graphics are just visually stunning.

And we only have three on the board here.

You have a total of ten?

And that's why I love this story, because on the tube we have, "Save these, Janet!"

Big exclamation point.

Pearl Jam, still performing today, has gone on for over three decades.

GUEST: The only reason that I brought them here today was because my friend who passed away last year, Nick Scott, he loved music, he worked in the industry, he loved art.

He and his best friend would try to find the coolest things, and he loved this show.

We've kind of taken on celebrating things that reflect things that he loved in his life, kind of to try to keep his memory alive.

This is a big surprise that you liked these, and I'm so glad that you did, because they're really special to me.

APPRAISER: Your friend Nick gave you something very special.

For the collection of the ten that you have here, it would easily be $10,000 to $15,000 at auction.

GUEST (tearfully): Wow!

(sniffles) APPRAISER: They're phenomenal.

GUEST: Thank you-- Nick was phenomenal.

APPRAISER: (chuckling): It's amazing.

Thank you.
