One of the most important images in iconic art, having strong iconographic and stylistic affinity, is The Mandylion, Icon of Icons, Holy Visage, or The Saviour Acheiropoietos. This image is considered to be the oldest known icon and also the oldest known portrait of Jesus.
This icon features the face of Christ as it was miraculously transferred onto a cloth to be sent to a king who was ill. This composition, also known as the Sudarium or Saviour Uncreated-by-human-hands, was said to have been sent by Christ himself to Abgar, king of Edessa. According to legend, this was the first icon, or “prototype” painted.
This image came to be regarded as a protector, a “bringer of victory”.
The origins of this icon go back to Russia, 12th century.
This Blue Mandylion is  Kashubian Mandylion.
At the four corners of the icons, are rich decorated motifs of Kashubian Region folk art, which symbolize the nature of Kashubian Lakeland province,” Blue Country,” abounding in hills and shores, rich in thousands of lakes, enchanted forests, wild flowers, in time buried  villages and small towns. The Kashubian decorative art includes seven main colors: three shades of blue, from light to dark – symbolizing the sky, lakes and sea, then yellow, red, green and black. The Kashubian art motifs consist of flowers, leafs and insects adopted from rich, native Kashubian nature.
