You may have never heard the name Gilbert Baker before, but you certainly have seen their artwork.

Way back in 1978, he designed what we now know as the Pride Flag.

And in the summer months, his design is basically inescapable.

It hangs off buildings, covers t-shirts, stars and commercials, it's everywhere.

But there's one building in San Francisco's Castro district,

for pride season is all year long.

We get walking tours that come by and they look at the plaque about Gilbert.

This is John Inck whistle.

He was a long-time friend of Gilbert.

And they stop and take pictures of the flag and

Instagram it and all the time night and day people pose in front of that flag.

It's a it's a powerful symbol.

In 2017 artist April Berger was commissioned to transform the garage doors of a gray

three-story house into a gorgeous wavy rainbow mural as a tribute to Gilbert and his flag design.

It's stunningly eye-catching. Visitors are constantly stopping and staring at it.

I happen to be traveling through the Bay Area and wanted to stop by and see it for myself.

I'm in the historic Castro District of San Francisco.

I just turned right on 17th Street.

I'm in front of the house.

In front of the mural.

If you look up, there's a pride flag.

But what I found there was more than just a pretty painting.
