LEGO Ideas Tales of the Space Age 21340 – Space-Themed Postcard Build Kit for Adults 18+

A Space-Themed Build Experience for Adults

Turn your table into a portal to the cosmos with LEGO Ideas Tales of the Space Age (21340). This set invites you to craft four connectible, brick-built 3D postcards, each capturing a distinct space scene that nods to 1980s sci-fi myths, movies, books, and posters. With 688 pieces, the building journey delivers tactile texture, satisfying clicks, and a tangible sense of accomplishment as the scenes come to life.

What you’ll build

• Four connectible 3D postcards, each a standalone scene or part of a larger constellation of images
• Scenes include an observatory viewing comets and shooting stars, a moon base with lunar eclipse, a space shuttle cutting through space, and a dramatic black hole
• Postcards feature separate building instructions, so you can build solo or collaborate with others

Display and arrangement

The postcards are designed to be freestanding on a shelf or table, or hung on the wall using the back hangers. They can be connected in any order, allowing you to curate a mini-gallery of space stories that suits your space and mood.

Design notes and graphic flair

Expect a minimalist, retro-modern LEGO aesthetic with bright accents that evoke vintage sci-fi posters. The pink/purple postcard offers stars that you can arrange to mirror familiar constellations—Ursa Major, Cepheus, Ursa Minor, or Cassiopeia—adding a playful, collectible touch.

Who this is for

• Perfect for adults 18+ who love space, astronomy, or art
• A thoughtful gift for birthdays, holidays, or as a display-worthy desk companion
• Great as a group activity for families or friends who enjoy hands-on creativity

What you may gain from the build

• A tactile, mindful project that unfolds piece by piece as you assemble
• A versatile display you can showcase on a shelf or wall, individually or as a connected set
• A collectible, conversation-starting piece inspired by space exploration and retro aesthetics

Whether you’re seeking a relaxing solo build, a collaborative project, or a striking display piece, Tales of the Space Age offers a tactile journey through space that complements both collectors and casual builders alike. The 688 pieces come in a compact kit that’s easy to store and enjoy at your own pace, with each postcard presenting a complete scene while inviting future connections with the others.
