An arm holding a giant gun appears to explode through a wall, while elsewhere a man walks a tiger on a leash. These breathtaking pencil drawings are the work of 31-year-old artist Ben Heine, who lives and works in Rochefort, Belgium.

Ko Min, 26, manually extracts oil from one of three 300 feet deep wells he works on in the Minhla township of the Magwe district October 27, 2013. Everyday, Ko Min makes around $30 extracting crude oil from three small wells after he bought rights to use them for close to $1000 from a farmer who owns the land. In Myanmar, an impoverished country rich with natural resources, people from poor communities find ways to supplement their income by exploiting such resources, such as the Minhla township, traditionally rich with oil, often using primitive and dangerous methods.

“The Pugs of Westeros” sees Roxy, Blue and Bono playing doggy versions of the main characters, including conniving King Joffrey.
