Review for LEGO set 10363 Leonardo da Vinci's Flying Machine from Brick Fanatics
“That includes a 2×2 tile printed with one of da Vinci’s schematics for his ornithopter (he sketched up more than 500 in total, or more than the total piece count for 10363 Leonardo da Vinci’s Flying Machine), and a handful of parts making debuts in new colors. The curved bar... More with a 1×1 plate at one end and an axle at the other, typically used in trans-clear for posing superhero minifigures, comes in brown here for the first time.”
