If you haven't heard about the LEGO Ideas Steamboat Willie set, I want to tell you about it real quick. Partly because there are 2 unique things about it: 1) there was a number error on the original release of the boxes and 2) there are creator signing dates... one which happens to be 2 days from now! 
Just to catch you up if you've been living under a rock, here is a short description of the LEGO Ideas Steamboat Willie set:
Disney Mickey Mouse fans will love this LEGO® Ideas 21317 Steamboat Willie building toy marking the 90th anniversary of the most famous cartoon character ever.
- The iconic Steamboat Willie boat features a black-and-white color scheme, hidden wheels, moving steam pipes, rotating paddle wheels, adjustable crane and assorted elements including the 'S.S. Willie' boat name sign, '1928' year sign and a 'potato bin'.
- The boat's bridge has space for a minifigure, a brick-built bell and assorted elements including the ship's wheel and life buoy.
- The 2 steam pipes move up and down and the 2 paddle wheels rotate when the boat is pushed along.
1 - The Numbering Error
LEGO Ideas boxes come with sequential number on the front of the box. This is to let you know what number LEGO Idea the box is. Turns out, the early boxes of this set show it as set #24. This is actually the LEGO Flintstones set. The Brick Show noted LEGO quickly released a statement saying:Due to our excitement to get the Steamboat Willie set into the hands of LEGO fans around the world as quick as possible, an error was made on the packaging relating to the sequential set number. It was mistakenly printed as #24 and it should have been #25. This will be corrected in future sets.If you get an early box and it says #24, you should keep that puppy. I suspect it will be worth some money soon enough!
