This postcard is part of our exclusive series created from punch card documents uncovered in the dusty vaults of the U.S. National Archives (NARA). Once used to power early computers and recordkeeping systems, these fragile cards sat untouched for decades — until now.

We've digitally restored and preserved these relics of bureaucratic history, transforming them into collectible postcards that celebrate a lost analog world. Printed on heavyweight 300g glossy stock in the DIN A6 format (4.1 x 5.8 inches), each card is a slice of mid-century government tech — delivered to your door.

Each card features our signature NARA design. The full story behind the original image is included in this listing.

**Historic Postcard: Allied Bombers Attack Blechhammer Synthetic Oil Plant** This postcard features a dramatic image of Consolidated B-24 Liberators from the 15th Air Force during a bombing raid on the Blechhammer synthetic oil plant in Germany. The plant, fueled by rich coal from Silesia, was a crucial part of the German war effort. The image captures the intensity of the attack, with bombers flying in formation and releasing their payload. The accompanying text describes the strategic significance of the 15th Air Force's campaign against the Silesian plants, including Blechhammer and Oswiecim, which were targeted in a series of 59 attacks that dropped nearly 15,000 tons of bombs. The text highlights the impact of the Allied air superiority over the Luftwaffe and the release of the 15th Air Force from their duties bombing Ploesti, allowing them to focus on the Silesian plants. The campaign, which began in July and intensified in September, dealt a significant blow to German industry, preventing the plants from achieving full production.
