Barcelona have presented the mosaic that will be shown in the stands before their game against bitter rivals Real Madrid.
Nearly 98,000 fans will be involved in creating a spectacular image showing a Catalan flag with the word 'Barca' emblazoned in the middle.
The design will be unveiled as the players walk onto the pitch ahead of kick-off, and it has similar style to the first ever mosaic shown at the ground exactly 20 years ago, which also only contained the word 'Barca'.
Previous designs have included messages of thanks to the team towards the ends of campaign and one which read 'We Love Football' at the 2011 Champions League final, which was held at Wembley.
The Clasico at Camp Nou kicks off at 19:50CET on Sunday.
