RM 5: RADIO
It is the advertising of
Radio Centouno (101), that uses a mirror image only for that number.
The digit 1 is easily
readable even as mirror printed, the 0
does not changes in the mirror way because it is perfectly symmetrical both in horizontal and vertical.
The choice of the number presentation in opposition attracts the attention, does
not creates any reading trouble, and the
decoding of the mirrored figure happens
suddenly in the following of the layout.
Its memorization then becomes reinforced.
