If you saw the announcement for the LEGO Ideas Steamboat Willie (21317) set, you may have saw that it was labeled at set #24 in the Ideas line. More keen-eyed readers may have noticed that it is the same number as the recently released The Flintstones (21316) set as it is also #24. This is an error on LEGO’s part and they have released a statement about it.
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.
The first run of sets will have the error on the boxes so if you’re particular about that kind of thing, then you’ll be glad to know they will be fixing it in later releases. For those who are getting it when it comes out in April, you will be getting the error boxes and may be a bit more valuable later on when the set retires since there are people who do buy error stuff from LEGO.
