The back designs of the Aviator cards are in two different colours – red and blue. Actually the back colour determine the marks.
The red cards are marked with big letter or number in the middle, or with small fonts in the corners. The marks are also in different colours. You can find the red cards with black or white marks.
The blue cards are usually marked just with a big font in the middle. And the ink used for the marking is white.
The Aviator marked cards are made of plastic coated paper material. These cards are jumbo indexed and the card size is 2.5" x 3.5".
Each deck contains 52 cards and 2 jokers. There is a card to certify the guarantee, as well.
