Anyone after ~7 years still interested?
This is the backside of the 1993 Town Mini Catalogue from the US. (Front here: https://www.bricklink.com/catalogItemPic.asp?C=m93usto2 )Seems there were to kinds of all Legoland themed Mini catalogues in 1993: The normals backside with all the other themes and this special-offer backside. Also it seems that this idea from Lego was only half-assed launched in the US and only for two years, though the instructions were the same across the world.
A question remains though: what does the colour-code in the instructions in the place were the points were from 1994 onwards mean? There are blue corners as well as yellow and red ones. Any ideas? :)
