Modelled after the original in the Unlocking History Materials Collection.
The letter substrate is reduced to a letter-packet by first making three diagonal folds: first, the bottom two corners are folded towards the center of the letter sheet, thus forming a triangle; their edges meet but do not overlap. Then, one of the top corners of the letter substrate is folded to abut the long base at the top of the triangle previously formed.
The substrate is then flipped over and rotated so the two right angles are at the bottom. It is then folded into three equal parts, using rolled folds, starting with the bottom edge. The tip of the top panel sticks out, so it is folded back in the opposite direction. The panel on top then tucks into one of of the triangular-shaped pocket panels that has formed. In its folded and closed state, this letter has several surfaces that make up the two outermost panels; many panel surfaces are exposed.
This letter was sent from Poland to Chicago, IL USA in the late 1950s between two family members. Our example is in an envelope, however we expect there are examples of this letterlocking variation without an outer wrapper or envelope.
