In June 2011, we were delighted with the big mistake made by LEGO on the sticker of the set 10221 Super Star Destroyer (turbolaser became Turoblaser - See this article). The error had been corrected for the effective marketing of the set.
But this is not the first time that LEGO has made a blunder that still leaves a mess for a leading manufacturer in its field. Especially since the error on set 10221 had been present throughout the product promotion campaign by LEGO.
When the set is released 10179 Ultimate Collector's Millennium Falcon in 2007, an error of the same type had slipped on the presentation sticker. number of Quad Laser Cannons was 12 on the sticker produced initially and has been corrected to 2 thereafter.
It is difficult to know how many sets with the error are actually circulating, many owners of this set have never even opened it and probably never will, hoping instead for a resale with a good margin the day they feel that the price has skyrocketed sufficiently.
However, you can afford this collector sticker with 12 cannons for the modest sum of around 90 euros on bricklink, some vendors specifically offer this version.
