Modelled after Simkin G.(/?) Russian triangle letter from Field PoBox 03142 to Simkin M.M., village Pinny (?), Northern Pecherskiy district, Kirovsk region, military base 274, (1944), MIT Libraries, Unlocking History Materials Collection. Before folding his letter into a distinct triangular letterpacket, this World War II Russian soldier wrote home to his parents, letting them know that he was well and that he had received their letter. He informed them that he had recently joined the Communist Party of Russian Workers and asked them to send more detailed news. After writing the letter, he created an edge fold by folding the left long edge in on itself about 35mm. Along that edge is what appears to be a loss from a burn. He then created a diagonal fold by aligning the top right corner of the paper with the opposite long edge. He created another diagonal fold, this time with the top left corner. These actions created a triangular-shaped pocket. He folded the bottom two corners of the letter, aligning one edge of each corner with the bottom edge of the larger triangle-shaped panels. The bottom trapezoid shaped panel tucked into the triangle-shaped pocket to create the letterpacket. Practical and economic qualities of letterlocking endured globally after the invention of the gummed envelope in the 1830s, including during and after World War II. This letterlocking variation features zero built-in security measures, perhaps for ultimate national security (the soldiers could not seal the letters or insert enclosures). The triangular formats made the packets easily identifiable and easy to open and close for censoring before returning to their closed orientation for processing and transport through the postal system. This letter is essential to the study of letterlocking because it demonstrates that letters can remain closed and travel in the post without the use of adhesives such as sealing wax.

We have news! Since this filming, our team of 11 researchers worked together to read an unopened letter virtually – the words and the folds – for the first time, without ever breaking its seal.
