|Redesigned during production.|
There are at least 2 different versions of instructions for this set. The differences for the second version are indicated in this inventory in the Alternate Items section with Match ID 99.
Quick overview of redesign: Eighteen 2 x 2 x 3 bricks are replaced by eighteen 2 x 2 bricks and thirty-six 1 x 2 x 2 bricks. A supplementary sheet also shows (independently of both early and late instructions versions) two dark bluish gray 75 degree 2 x 2 x 3 slopes being replaced by four 2 x 1 x 3 slopes of the same color and angle.
The cards are only available in sets purchased in the North America region.
