Nostalgia bomb, incoming. This delightful build from Jonah Schultz is three things in one: a tribute to timeless preschool toys, an homage to the ubiquitous I Spy puzzle books from the ’90s and a showcase of an Iron Builder‘s ingenuity with LEGO bricks. There are so many details to love, from the perfectly proportioned BRIO trains in primary colors to the wonderful debossed lettering on the alphabet blocks, to the judicious use of specialized elements like the Bellville teddy bear, Duplo balls, and Race Car Guy accessory to complement the studs-free build. The most impressive feat of all is how the seed part – baseball bat in silver – is incorporated into the build as train axles, domino pips, and a camera button. And it’s a hidden object puzzle! Can you spy all of the secrets hidden in the picture?
