The designs were reviewed by an independent panel made up of representatives from Luton Borough Council, Luton Arts and Culture Strategy Group, and Luton Heritage Forum.
It was funded through UK Shared Prosperity Fund (UKSPF) in collaboration with the council and the Step Forward Luton partnership.
James Taylor, a Labour member of Luton Borough Council with a responsibility for regeneration, said: “Sarah’s vibrant mural has wonderfully transformed the cinema’s frontage, giving the building a much-needed refresh while it awaits longer-term development.
“This is just one of many positive developments planned for the town centre that will help to ensure that investors and businesses see it as an area where people will enjoy living, visiting and working.”
