For kids
A poster is the easiest thing to swap in a child's room: it costs less than a picture, and a year later you change the sheet and leave the frame on the wall.
504 designs. 200 g poster paper, formats from 21×30 to 90×60 cm, from 49 zł. A poster ships unframed — you pick the frame yourself, which is the cheapest way to change a wall once a season.
