Not sure if this deck is still being printed, but I think it is - you should contact the printer (Lo Scarabeo) and tell them your deck didn't come with one, ask them to please send one to you.
I've just kindly had a response of a lwb to be sent to me so wanted to say thank you. I am really amazed at how friendly and helpful everyone is so quickly. It's great to be here.
sunshineKdb: Do what Bhavana suggests, which is to contact Lo Scarabeo directly (they have a website). They respond promptly and should send you a copy of the LWB soon.
(By the way, I own the deck but it's not with me now, and as with most LoS decks the LWB is basically useless, so in truth you're not missing anything even without it )
LoS and their LWBs... was just thinking of that cause my deck of next week is the Circle of Life and it is like 78 proverbs that may or may not have something to do with whatever is on the image
