Thousands of football fans gather in Mexico City’s Zócalo to take part in a Panini-organised sticker swap linked to a Guinness World Records attempt. The event brings together collectors of different ages as they trade and exchange official 2026 World Cup stickers, aiming to build the largest collection or meet a specific swapping-related record criterion set by Guinness. Reports say the gathering turns the search for missing stickers into a community activity, with fans meeting in a public square to swap duplicates and complete their albums. Organisers describe the swap as a celebration of football and family participation, with attendees using the event both to negotiate trades and to enjoy the occasion as a shared fan experience. The coverage highlights the scale of the turnout and the focus on record-setting within a widely recognised collectors’ hobby. The attempt is presented as an official effort tied to Guinness World Records, with the sticker exchange serving as the core activity.
