Around 1992 (possibly, coinciding with the switch from Legoland to Lego System labeling on boxes?), Lego instructions started featuring a triangular marking in the corner of a page. On one side, that marking would show some graphical cue to the theme or subtheme, e.g.:
These exemplary markings are from the instructions of:
- 6401: Paradisa Seaside Cabana from 1992
- 6534: City Beach Bandit from 1992
- 6350: City Pizza To Go from 1994
- 6442: Divers Sting Ray Explorer from 1997
In the beginning, the other side of those markings contained what appears to be a points count (the larger the set, the more points it would contain):
Note how this side also contains the set number and the year - based on the instructions I'm looking at right now, I cannot tell whether it is the original release year of the set, or the year this particular instruction sheet was printed.
Oddly enough, TLC discontinued this "points" labeling not long after it had been introduced, but otherwise, the corner marking remained:
What, if any, was the purpose of those "points"? Once the points were gone, was there still any purpose to the triangular corner marking, or was it merely "traditional"/decorative by then?
