SAN FRANCISCO (KCBS) — Now that the Giants are headed to another World Series, fans are already scrambling for souvenirs. And right after Travis Ishikawa hit the walk-off three-run home run that sealed the team’s National League pennant victory over the St. Louis Cardinals, the presses at a San Francisco t-shirt printer have been rolling.

The all-night shift had about 40 printers running at the Graphic Sportswear factory in city’s Potrero Hill neighborhood.

“We’re going to print about 30,000,” Mike Smith, the sales manager for Graphic Sportswear, said. “Most of these are going to go to the Dug Out store in the stadium but also other retailers in the area.”

“When Ishikawa hit the home run, we had people her five minutes later,” Smith said.

A couple of employees had to be sent home because they fell asleep, he said.

The first few thousand t-shirts that read “We own the pennant, National League Champions” were printed prior to the game last night. Many of which probably are soaked with champagne and beer.

The t-shirt printing presses at Graphic Sportswear turning exactly 25 years ago on Oct. 17. 1989 during the Loma Prieta earthquake. Smith said that those Giants World Series t-shirts smudged as the ink splattered.
