Groucho, Gummo Marx autographed book

I have a 1950 book titled The Marx Brothers by Kyle Crichton. I recently found it at a thrift shop in NC. It wasn't until after returning home from my vacation that I read the handwriting on the title page. From what I can tell, it reads: "N.B.C. is much closer to the Brown Derby - and I hope I wind up that close." It says "to McConnell" and is supposedly signed by both Groucho and Gummo Marx. I contacted Stefan at marx-brothers.org and he believed the writing and signature was similar to Groucho's. He sent me a link to a published letter by Groucho referencing someone named McConnell and mentioned Gummo contacting this person regarding some matter, so I believe McConnell is someone who Groucho knew personally. I did my own research and the handwriting is similar and the signature is as well, though I found two different types of verified Groucho signatures online, so I'm not sure why he used a variation.  Thank you for looking into this! UPDATE: I typed in a search for McConnell and Brevard, NC, where I bought the book. Apparently Joseph McConnell was the president of NBC from 1949 to 1952, and also had a home in Brevard, where I purchased this book. I believe the inscription from Groucho is to the NBC president.
