this cards are probably most popular deck in my part of the world!
)
and called *gypsy tarot!
) lolz
I find it to be surprisingly on spot in reading when I used it first time! as even with only 36 cards that are simple as possible it worked similar to tarot for me!
)
even it's reading system is more similar to lenormand/meaning is always the same regardles card design and all cards have titles but difference is there is no numbers and card insertions,
and you can read book sample here

imo it's a best book for this specific cards!
) but will you find it useful? it more depends on how do you feel about your deck? if you like using it and reading with it then go for it!
)
if not i don't think book will help?x,x
btw you can go for cheep pdf version I wrote for same cards
