Abstract (en)
[origin: FR2776082A1] the table uses dual images to show two currency values in same positions.- DETAILED DESCRIPTION - The exchange rate table comprises a small rectangular table which is subdivided into a rectangular grid. Each cell on the grid contains a pair of numbers indicating a quantity of a first currency. The cells are numbered in a sequential pattern. The number pairs are only visible when the grid is seen from a first tilt angle. When the grid is seen from a second, different tilt angle the equivalent values in a different currency are seen. It is possible to offer a third viewing angle, which can allow either a third currency to be seen, or a conversion into the second currency at a different rate of exchange
