Galactus and a Cracked Case
A bought an affordable copy of Fantastic Four #48. It was a CGC 4.0 and budget friendly. I bought it from a dealer with whom I have had many successful transactions. The damn Postal Service crushed the box and cracked the CGC case. Holy cow, I was hot. Luckily the dealer took care of me, and CGC is reslabbing it.
First appearance of Galactus deserved to be treated better by the USPS.
