CHICAGO — Your next Instagram post just dropped: pic with the Pope.

As Sox fans stroll under the viaducts at 430 W. 35th St., they’re welcomed by the faces of team legends and a rich tapestry of baseball history leading up to the gates of Rate Field.

Now, thanks to Loyola Press and artist Cyd Smillie, a new Chicago phenomenon joins their ranks: none other than Pope Leo XIV.

The new Pope Leo portrait has been added to “The Dream” mural, and it tells the story of Little League players dreaming of hitting the perfect home run alongside important figures from Chicago history.

The addition is just in time for a celebration and Mass in the pope’s honor Saturday at Rate Field . The pontiff will participate remotely from Rome, addressing the people of Chicago. The event will include music, prayers and testimonials. Tickets sold out within minutes.

Chicago-based Loyola Press will publish the first book on Pope Leo in July: “Pope Leo XIV: Inside the Conclave and the Dawn of a New Papacy,” by Christopher White. The publisher contacted Smillie, alerting the artist it would sponsor the addition to the mural. Through the collaboration, Smillie was able to add Pope Leo alongside the legends.

“As a publisher rooted in Chicago, we are especially moved that the Holy Father hails from our city before he went on to serve so faithfully in Peru,” said Joellyn Cicciarelli, president and publisher of Loyola Press.

Smillie has worked on perfecting the mural and cleaning up surrounding pieces since Monday, just in time for this weekend’s big event.

As you pass by, you’ll spot Pope Leo XIV striking his iconic conclave wave — only this time, he’s wearing a Chicago White Sox cap. It’s a bold blend of tradition and hometown pride, and Smillie said the neighborhood couldn’t be more excited.

“Since I’ve been painting here, every half-hour at least, somebody stops by to take a picture,” Smillie said. “At one point, it was just white, and all I had was pictures up, and then— ‘Oh! Oh! The pope!’”

Pope Leo grew up as Robert Francis Prevost in south suburban Dolton and attended church on the Far Southeast Side. He served as principal of St. Gabriel School in Canaryville — deep in White Sox country. The future pope even attended a White Sox home game during the 2005 world series. His lifelong loyalty to the Sox — now immortalized in the mural — is a point of pride for South Siders.

At Saturday’s celebratory Mass, there will also be a free-standing cutout of the pope with which attendees can take photos. Smillie will be painting signs, and fans can keep an eye out for the “Pop-Up Pope” on the train, around the stadium and throughout the city.

Loyola Press is also inviting fans to participate in “Pic With the Pope” by taking a selfie or photo with the Pope Leo XIV mural or the Pop-Up Pope and posting to social media with the hashtag #PopeLeoXIVinChicago.
