Pegase 55 is the largest standard carry on you can take on the airplane, one of the iconic travel piece by the house of Louis Vuitton. I owned this luggage for years, but it has been well maintained with care and love. It's in great shape with all accessories, original receipt, locks and keys. It's retail price is around $4000 now, definitely it's a collectible piece.
