Objects of Desire: Vintage Helmet Bags

Lately I have been trolling around ebay a lot, looking at these awesome vintage helmet bags that come up for auction from time to time.  Somewhere in the far reaches of the internets are folks willing to shell out top dollar for these things. I am consistently astonished at how high the ending bids are on these items. Above is a compilation of some of the best ones I have seen on ebay so far. The upper left one is actually NOS from the 60s and had a buy it now price of over $600! Funny thing is, they aren't real leather and they are really poorly made.  BUT THEY ARE SO COOL! I want one!
