It's not a bad looking calendar, although I find it a bit unconventional to have the dates split between the two open pages. That's not a big deal though.
But the paper it's printed on is thin and low quality - the sides of the top page flops down, looking like the ears of a sad dog. I'd really expect more from a Lonely Planet product.
Besides that, I like the idea - it's fun to read about different places: makes you nostalgic for the ones you've been to, and curious about the ones you haven't. However I'm not sure about the result - I have to say it's a bit bland. The colours aren't very exciting, nor the font or design, and the pictures and texts themselves don't quite make up for it.
But overall it would be a perfectly alright calendar, if it wasn't for the paper quality. If that was better, I'd recommend it. As it is though, no, sorry, I can't recommend it.
