This is an original vintage copy of Detective Comics No. 257, published in July 1958 by DC Comics. The issue features a classic Silver Age Batman and Robin story titled "Batman's Invincible Foe!", introducing the sci-fi villain Karko. The iconic cover art depicts Batman and Robin on the Batmobile facing a futuristic flying saucer menace. The comic is in good vintage condition, showing typical signs of age and wear. This includes some spine wear, minor creasing along the edges, and light tanning of the interior newsprint pages. The staples remain secure, and the cover retains much of its original color. The back cover features a classic house ad for DC National Comics. A fantastic addition for any serious collector of Silver Age DC comics, Batman memorabilia, or vintage pop culture. Please refer to the photos to assess the detailed condition of the spine, corners, and pages.
