#4999 Wind Turbine Vestas promo set, if LEGO ever got into the market of making "marketing sets" like this for big companies, it would drive LEGO collectors mad with murderous glee.
I personally think this calendar looks cool... I'd buy one, even if it isn't LEGO. And here's another type of clone brand calendar. Found on darkroastedblend.com. BTW, just checked eBay, there's none listed at this time.
Update: You can buy your own clone brand calendar here.
