Postcard details: Boxing - Blue Cats by Rina Zeniuk (MyMagiCard), travelled about 2537 km (1576 mi) in 17 days

Rina Zeniuk (Рина Зенюк), based in Minsk (Belarus), is an architect by education and an illustrator by profession. Her favourite genre is 'catism' and she is famous for her "Blue Cats", which have been so beloved that they have been transferred to postcards, notebooks and more, and now they are sent around the world. Real cat life is intertwined with fantastic illustrations of cat life. The artist's fantasy takes the viewer into the bizarre world of Blue Cats. Her illustrations are striking in the originality of the plot, as well as the quality of the drawing.

Catism is a micronational form of belief in which people worship cats.
