Eagles fans celebrate Super Bowl one more time at Penn’s Landing

Hours before the Eagles took the field at the Linc for their season opener vs. the Falcons, a sea of green-wearing Birds' lovers had gathered at Penn's Landing to celebrate the 2017 champions. They took photos, got autographs, bought Eagles gear and generally basked in the feel-good vibe that only the city's first Super Bowl win could provide.

The daylong event, dubbed "2018 NFL Kickoff," was capped by an evening concert by the Canadian singer-songwriter Shawn Mendes, who has become a Billboard-charting star since his days of posting covers on the video app Vine. Mendes performed "There's Nothing Holdin' Me Back," "In My Blood," and other hits for an enthusiastic crowd.

Before the concert, fans braved the heat and humidity, standing in line for a chance to take a photo of themselves alongside the Vince Lombardi Trophy, or have a quick peek at a collection of Super Bowl rings, or get autographs from former Eagles including fan favorite Brian Westbrook, who earlier awarded tickets for next year's Super Bowl to a married couple who had never attended an Eagles game.

There was no shortage of team apparel. Among the decked-out crowd was longtime supporter Alvin Dean of Willingboro, who was sporting a homemade cane studded with Eagles pins, and Justin Gonzalez of North Philadelphia, who also was wearing team colors.

“I go to sleep every night and it’s –” Gonzalez said and paused. “It’s still real. The Eagles are still world champions.”
