Publisher profile coming soon
Marvel revolution. Stan Lee, Jack Kirby, and Steve Ditko create the modern superhero. Spider-Man, Fantastic Four, X-Men debut.
The sweet spot for collectors — significant enough to be culturally important, scarce enough to be valuable. 9.8 copies are extremely rare.
Inspectable mathematical proof, blockchain/ledger provenance, data integrity validation, and asset taxonomy.
In illiquid alternative asset markets, sovereign blue-chip holdings trade at an exponential multiple over mid-grade float due to institutional accumulation and inelastic seller reservation prices.
Tom Tanner, a young trouble maker on the run to escape having to go to reform school ends up in Smallville, and upon discovering that he resembles Clark Kent decides to pose as Clark (who is otherwise busy on his daily activities as Superboy.) This ends up working on Superboy's favor as Lana Lang is once again trying to prove that Clark Kent is Superboy by having one of her classmates cut his hair. Lana is shocked when "Clark's" hair is cut, and "Clark" punches out the prankster. Meanwhile, Superboy is met by a person appearing to be Sun Boy of the Legion of Super-Heroes from the 30th Century. Sun Boy tells Superboy that recently the Legion obtained a super-weapon made by a recently deceased criminal scientist and had it disassembled into seven components, those seven components were then put in lead casings and hidden in different locations in the 20th Century so that no criminal in the 30th Century could reassemble it. Sun Boy goes on to tell Superboy that as part of his Legion initiation was to collect the components and bring them back to the 30th Century because the Legion later realized that the weapon could be used by criminal in the 20th Century as well. Superboy agrees to help Sun Boy collect the parts of the weapon, and with every part in his possession Sun Boy leaves Superboy to return to the future. However, it turns out that the person who Superboy has been helping is nothing but an impostor and tricked Superboy into helping him. While "Sun Boy" assembles the weapon (A robot that has a ray beam that can turn people evil), Superboy returns home to find Tom Tanner in his place. When Martha unknowingly reveals Superboy's identity to Tom to try and get him to put out a grease fire in the kitchen, Tom reveals his true identity to Martha and threatens to reveal Superboy's identity should she try to ruin his cover. Meanwhile, "Sun Boy" sends the cyclops robot to turn Superboy evil with it's ray. However the robot blasts Tom Tanner instead. Superboy and Krypto then follow the robot back to the fake Sun Boy and destroy it, before Superboy takes the faux Sun Boy into custody and returns him to the 30th Century. There he reveals him as a fake to all present. Revealing that he determined "Sun Boy" to be a fake when he didn't initiate the Legion hand shake when he first met Superboy. Returning to his own time, Superboy resumes his Clark Kent identity, and learns that Tom -- after recovering from the blast from the robot he received -- has now become good and as a side effect his memories of Clark's true identity were erased. Tom thanks Martha and Clark for steering him back on the straight and narrow and leaves to return to the reform school which he was fleeing from.
Strict algorithmic segregation separating clean single-issue Cover A sales from multi-issue lot bundles, retailer exclusives, and foreign variants.
A fake Sun Boy comes to Smallville asking Superboy's help in assembling a super-weapon. Meanwhile Tom Tanner, an escapee from reform school, takes over Clark Kent's identity.
A man's hair doesn't stand up because it's a wig.
The Bizarros celebrate when their world is invaded by animated blue kryptonite creatures, until the invaders try to make it round again. Then war breaks out. The blue kryptonite radiation was not blocked by regular lead suits, but is blocked by imperfect duplicates of the same lead suits.
Borrowed umbrella clearly marked with Shorty's name.
