Showcase 🔥FOR SALE🔥 2nd Appearance of Challengers Of The Unknown Cover Art by The Legendary and ☝️ and only Jack King 👑 Kirby The Man is Untouchable in his time and now in my opinion. This comic as you all can see is pretty beat up 🤕 as a matter a fact to me it’s a .5 even though it’s complete nothing missing at all but you do have a piece missing on the front and back cover and the cover is loose 😢😭😩😫. But still is a treasure to have 😊. Another reason I picked this comic was because I have seen 2 gentleman that I follow with a comic from each about so hopefully they are both fine with me adding this 1st Appearance of this big over grown called Ultivac. DM me for details, shipping available and PayPal or cash excepted 😊
