Apparently I did see this book in person in Chicago at Bedrock's booth. A very nice 5.5 and perhaps upgrade potential.
Many years ago, that copy was originally unearthed by our own Flex Mentallo (who I hope will correct me if any of this is in error). Around 2006, he sold it to a collector named Joe Serpico, and it was Joe who had it slabbed. Joe Serpico is responsible for a great many Baker romance books in the CGC census. In most cases, where only a single, low grade copy of a particular issue has been graded, it's usually due to Joe. He'd eventually acquired almost every issue of the St. John romance titles, and he slabbed them all in short order, the low grade and the high grade alike.
Joe paid a lot for my Bakers. (The money went to my project in India) I was very surprised when he let them go.
