This B17G was purchased with war bonds bought by staff and employees of the famous Anheuser-Busch Co, brewers of the popular Budweiser beer. The funds were contributed in 1944 but the airplane was another of the War Dept's airbrushed photos of the silver B17G taken at one of the manufacturing plants and it is almost certain that an actual B17 was never painted with such a title.
Aircraft losses at the time were such that replacements had to be immediately despatched to the war front and no time could be spared for elaborate christening ceremonies the likes of which occurred in the earlier months of war.
Anheuser-Busch employees raised sufficient funds for a second B17G named 'Buschwacker', but this too was an air-brushed publicity photo. In both cases the original photo was carefully staged so that no identifying serial number can be seen. Thus the same basic image could be used several times amended to show different war bond purchases.
