I can only begin to imagine what it must feel like to own a copy of Detective Comics #27. It's a book so legendary, so important to our hobby, that I would be thrilled beyond belief to own just a single non-Batman page.
Yours is not only complete, but has its cover, and is about as sharp as any collector could ever hope for. This to me is an example of restoration gone very VERY well. It also presents so well within the CGC slab; you must be one proud owner.
I don't want to sound overly cheesy, but could you describe for those of us who have yet to (and might never) own a Tec #27, what the feeling must be like to finally have the privilege to own a book of that magnitude?
Sorry, but cheesy is what you'll get -- how about owning a book you want to just look at and hold anytime you are within 100 yards of where it lies ?? How about picking it up in the holder so gently as if you were picking up the actual book, not wanting to damage it, what about wanting to sleep with it under your pillow every damn night an.................OK, sorry, too much information.
That's how anyone would be.
