Thank you very much Skinny, and everyone else. I couldn't find the book on the website, unfortunately. All the guy told me, that I bought the book from, was that he found in his house's cellar, in a box of other Czech items, mainly religious. I myself am Polish, and I speak and read it, and so, since Czech is very close to Polish, I made out that this is, in fact, a first communion book, possibly for children going into first communion. I would think that this book may be worth the most for a collector of foreign religious books. Even if the book isn't worth much, I hardly paid anything for it, but I picked it out because of the cover. I've seen many 1800's era books, and I have a few myself, but I've rarely seen one with such a detailed cover. Whoever had this book must have probably treasured it.
