This is a small message postcard sent by Verlag für Militär- u. Fachliteratur A. Franz Göth & Sohn from Vienna to inform a customer that the delivery of her order 'Der grosse deutsche Feldzug gegen Polen' (The Great German Campaign against Poland) will take longer. The postcard is approximately 10.5 x 15 cm. Unfortunately, the card is slightly damaged (a wrinkle in the center); see the scans. Nice original item!
