Warning: The following fact will make you feel old. Classic baseball and kids film The Sandlot is 20 years old this year. To mark the movie’s anniversary, footwear manufacturer PF Flyers created an interactive application for its Facebook page.

Facebook users who like the PF Flyers page can access its Sandlot app, which allows them to upload photos of themselves, create custom baseball cards, and determine their player personalities.

The app also informs users about the schedule of a tour of ballparks around the country marking the 20th anniversary of The Sandlot.

Boston-based social and interactive agency GY&K Antler created the Sandlot app for PF Flyers.
