Dual-Exposure Photo-Grid Tribute Poster (Mixed-Media Textures)

Create a premium sports-style conceptual tribute poster with Nano Banana Pro: a high-contrast B&W portrait silhouette as the vessel, filled with a dense action-shot photo mosaic grid enhanced by halftone dots, fabric/embroidery, and film-grain textures—finished with restrained selective color accents and strict micro-scaled branding typography.
