Two dressmakers pattern making rulers - both marked as 'Le Grand Chic' Brevetto N 38434 Giuseppe Perazzolo Bologna.
They have different shapes cut out of them so are not exactly the same. Fold out into a larger triangle piece.
Some damage to the points - with splitting to the layers of the wood and small pieces missing from the points. Pen marks in spots. One of the rules is a little warped but can be pressed flat so remains functional.
