These awesome outer space and city-themed prints by Push Pin for Kokka come with an unintentionally depressing message. Spotted at This and That From Japan and+Matatabi on Etsy, and at Superbuzzy. Push Pin is also behind the Eau de Mer collection, the popular faux Lego print (also with the Hello My Friend characters), November Books, and more.
P.S. It has come to my attention that Kokka typically only prints 1-2 colorways of each print; for instance the top print comes in that bright multicolored version and a monotone blue. Any others are knockoffs, so beware!
