Reviewing the book's mock-up

I have been spending the past two days looking through the mock-up of Let the Aisles Proclaim. Searching for some last-minute errors or enhancements to the pages before giving the word "Go" to the printers to proceed. A nervous process, this, as once the go-ahead is given, there is no turning back! So far, everything looks good. I did uncover some minor improvements and the layout designers have already accommodated me. At this late stage of the book production though, I have uncovered one more picture which would be nice to have been included into the book but the deadline is looming and I can't afford any more delays.
