I recently came across this fantastic 30-year-old calendar at my grandmother's house. From what I can tell, it's from United Bank Limited, a Pakistani bank with branches worldwide. She picked it up while living in Bahrain for several years in the 1970s.

Each of the 31 pages depicts the current date (1-31) in Arabic-Indic numerals - which in many cases have a striking resemblance to how they're rendered in the European manner. However, being a designer, what I fell in love with was the sheer graphic impact that each page had.

Each numeral acts as a mask, revealing an abstract painting or pattern. In stark contrast to the numbers, each page has a small line drawing, which seems to have some relationship to the painting or pattern. Overall, I find the entire thing to be just beautiful. I love the idea of having a piece of art that changes each day act as something functional.
