Authentic with original tags and receipt. Balenziaga Motocross Giant Hobo from 2009. The bag is beautiful lamb leather in a truffle gray color with giant silver hardware. Absolutely fantastic condition. See photos. No flaws to report. Clean inside and out. This bag is from my personal collection. I purchased it myself from the Balenziaga store at the forum shops at Caesars Hotel in Las Vegas. 
The bag comes with dust bag, mirror, receipt, tags.
