If there are still people who like to have real posters/calendars to mark certain events and things to do, I don’t know them. But I guess there are some, and this is something for them. A handmade memo calendar made in Germany by Snug Studio, available in white (darkgrey on white, specifically) and pink (pink on softpink).
It’s quite basic in design. The months are lined up horizontally and the days are lined up vertically beneath them. Every day has it’s own bracket to be filled by something you deem important and ought to remember. It’s made of paper and the size is 594 mm x 841 mm x 170 g. If necessary, people from Snug Studio will ship posters and calendars individually, and they ship it worldwide from Germany.
