Lenormand I believe are actually a formalized deck rather than being random like Gypsy cards. They usually a set of 36 card deck which have both a picture and playing card insert somewhere on each card, although the Mystical Lenormand put out by U.S. Games do not which is unusual.
In a way they are formalized gypsy cards usually with a playing card insert except Lenormand usually runs to a strict pattern below:
22. CROSSROADS/ TWO PATHS
Whether or not the cards are good depends on what is in front of each other and behind it – they are usually read in groups of either two or three together.
I have an additional two Lenormand deck which besides having the above cards have some additional extras. My second deck which I purchase direct from the artist Ciro Marchetti. The playing card insert on these is very small and sits in the right hand corner of each card. I only take note of the playing card on them when it is the Outcome Card to a particular question during a reading. This deck is called Gilded Reverie Lenormand.
The additional cards in his deck are: Dice, Clocks, Mask and Bridges.
My third deck again I purchased over the internet direct from the artist named Shades of Pink Lenormand deck coming from I believe Canada – Artist name is Lynn. This is an unusually large deck as it has 4 ladies; 4 men; 2 raiders (one being a lady); 2 children – one boy one girl along with some extras that one would normally find in a Gypsy Card Deck. Her extras are; YES, NO, CATS, PURSE, SEXUAL DESIRE, CLOCK. Unfortunately Lynn has since decided to close shop and I am very fortune in getting a deck from her before this happened.
