LEGO SYSTEM IM SPIEL 1957
TWO-COLOUR LEAFLET - A4 (2 pages) - 1st type
NOTE: this leaflet is probably
the first edition, printed on thick white paper, and goes for Jan Katanek
who explained to me the subtle differences between leaflet editions and
didn't blink when I commented that collectors were all crazy (or so my
wife says).
