This is an Iron Man Mark I armor mini papercraft, used by Stark to escape his captors, the paper toy created by Gus Santome. There is also an Iron Man Mark XLII Armor Mini Papercraft on PaperCraftSquare. The original armor, Tony Stark created the Iron Man Mark I while in captivity in Afghanistan. As such, it is crudely designed and bulky. It does have the necessary capacity, however, to help him escape his captors. It is bullet-proof, has two built-in flamethrowers, a rocket launcher, as well as rocket boosters for jumps. It is notable that this version of the armor, unlike the later Mark 2 and Mark 3 armors, does not have an on-board AI system or internal diagnostic display.
The helmet served only as a simple shield, and was not fully sealed. Stark refashioned the special iron-copper-magnesium alloy from disassembled Stark mortar cannons into the Mark I armor, rendering it especially bulletproof. To power the thruster boots, Stark reportedly siphoned the propellant fuel from four Stark S-class ballistic missiles into two Stark M-class mortars, creating two homemade fuel tanks, welded shut except for valves connecting fuel hoses that led down to the Mark I's legs.
