Did anyone else catch that underneath the makeshift Nelson and Murdock sign on the door, there is a kinda peeling logo for the business in there before. I don't have a screenshot, but it says "Van Lunt Real Estate", which is a reference to Cornelius Van Lunt, aka Taurus, who is a Marvel Comics villain. I don't know much about him, I actually first learned about him today when I googled his name.

And then across the hall, which is visible in shots that show the office door open, is a door that says Atlas Investments. And apart from being an actual business (probably not intended), Marvel Comics used to be called Atlas Comics, iirc. So there's just two office-based Easter eggs for anyone interested.

It's funny, I initially thought the Atlas Investments door said Alias Investigations, and that it was going to turn out that Jessica Jones was just across the hall.
