Cool little detail

My first time finding something like this, I saw the blueprint piece in set 60409 as I was building it and was confused so I checked the instructions and found what it was referencing in the back. I think I’ve seen a detail like this posted about for a different set but now I wonder how many other have small details like this (I’ve also never seen that video game roller coaster set before so I didn’t recognize it) submitted by /u/Jay_XERXES [link] [comments]
