(Lego minifig helmets by unknown)
This photo is awesome, not just from an artistic perspective but also from the contents, here we see an amazing stack of Lego minifig scale helmets and the structure of the inside of the helmets, Lego military helmets like the one shown are really popular with custom minifig builders who create world war 2 vignettes. Brickarms and Brick forge supply a good range of Lego headgear for several time periods, including roman, world war 1, world war 2 and modern. Additionally there are the usual fantasy and sci-fi genres as well.
Minifig helmets add an extra level of customization and personality to a custom minifig which should at least be considered when you’re designing your custom minifig.
