The mark consists of a rectangular background depicting a Greek village, with buildings having columns, domes and towers, the buildings outlined in light brown and colored green, light green, blue and light blue. Superimposed and centered on the background is a design comprising concentric ovals with their long axes horizontal, colored (respectively from largest to smallest) blue, white, gold, and variegated black and blue. ILOS is in block capital letters on the upper half of the innermost oval. The letters of ILIOS are outlined in light brown and are shaded from white at the top to light brown at the bottom. Black shadows of the letters of ILIOS appear below and to the right of the letters. A fine gold line, forming an oval interrupted at the bottom, surrounds ILIOS. A depiction of a brown ribbon, lined in white, forms a horizontal arc superimposed upon the ovals below ILIOS and extending beyond the left and right edges of the outer oval.
