Everyone wants to get into the act, as Durante used to say. Samsonite puts up the flag to show it has relatives in the service, too - the old suitcases of carefree pre-war days are footlockers now, card tables are ammo boxes. Chairs? They're scarce because the parts are being used to rain hell on the enemy.
As for the post-war marvels? Expect PLASTIC baggage!
Makes you nostalgic for a word when that had the promise of modern, scientific thrills.
