Walmart will have some exclusive limited edition vintage packaged LEGO sets to celebrate the 60th anniversary of the LEGO brick. There are three sets that will be available in the near future including the House (4000028), the Windmill (4000029), and a truck. All of the sets are priced at $19.99 each and collectors will most likely keep them in the boxes as they are pretty simple builds using common parts.
To go along with these sets, there’s also a promotion in which you can get a FREE collectible booklet and retro building instructions with a purchase of the LEGO Classic Bricks on a Roll (10715) set. Walmart will have an exclusive vintage packaged version of the set which you can see below.
Update: Added the image of the Truck (4000030).
