[상상한 미래] 1950년대 팝업북의 미래 도시

How a 1950s children's pop-up book imagined the city of the future, photographed straight on as an open pop-up spread: layered paper towers rising from the fold, a paper monorail on a pull-tab track, tiny cut-paper rockets on bent paper stems, clouds on paper springs. Flat lithographic printing in limited colours — turquoise, coral and mustard — with visible paper thickness, glued tabs and slight yellowing at the edges. Soft even light, a plain neutral background behind the book. No text, no letters, no numbers on the pages.
