Rare Superman comic found in house insulation

In this image provided by Metropolis Collectibles/ComicConnect, Corp., shows the front and back cover of "Action Comics No. 1" from 1938, featuring the debut of Superman, that was found by David Gonzales mixed in with old newspapers insulating a wall in a house he was renovating in a small town in Minnesota. Gonzalez did some research that confirmed the comic was valuable, though not as much as it could have been. He got into a heated discussion with a relative about its value, and the back cover got ripped lowering the grade to 1.5 based on a 10-point scale.

Writer Chinua Ac... Pallbearers carry the coffin of late author Chinua Achebe at his funeral service, held at St. Philip's Anglican Church in Ogidi, Nigeria, Thursday, May 23, 2013. Writer Chinua Achebe shunned Nigeria’s corrupt politicians and twice turned down national honors, never fearing to criticizing those he felt ruined a country he once supported breaking away from. On Thursday, however, the lawmakers and the country’s elite came to him. Hundreds attended Achebe’s funeral among the rolling hills of his eastern Nigeria home, a service that saw even President Goodluck Jonathan literally hold up the writer’s books. The gold plaque on his coffin simply called him the “eagle atop the Iroko tree” in his native Igbo language. (AP Photo/Sunday Alamba)
