You may have enough Superman action figures to populate Metropolis, or the sickest Man of Steel cosplay ever, or every Funko vinyl ever made in the image of Kal-el, but there is no Kryptonite for a Super-fan like a collectible you need to search infinite earths for.

Just try to obtain a figure that was only given out by DC to comic stores and distributors as a promo back in the early ‘40s, or a piece of original art that only one other fan ever got to own (and worship), or a certain movie poster variant so rare it wasn’t even included with the original promo materials. It almost can’t be done. Almost.

From unlikely gems that came out of cereal boxes to the rarest Superman comic in existence, these pieces of Man of Steel memorabilia will make you wish you had powers that could summon them.
