As a closet keyboard player I can only approve of this awesome lego and leather (now there's a combination you don't hear of every day) 'piano keys' handbag by Les Petits Joueurs. Its lego brick applique is firmly attached to the premium quality leather flap closure at the front, creating a fashionably elongated bag that I'd love to carry at a festival (when I'm rich!)
The bag, which is also available in all black, is the brainchild of Mariasole Cecchi, a 23 year-old accessories designer from Florence. She uses genuine lego pieces in her bags, having originally used them to resurrect an old clutch bag she'd dumped at the back of her wardrobe. She transformed it by creating the word 'Love' from bricks which she attached to the bag. and the concept for Les Petits Joueurs (the little players) was born. You can see her original 'love' bag here.
