At first the 8.5x11 Lo appears to be part of the 12x12 page. That was by design. I did not want photos from the 12x12 layout to create visual clutter and distract the eyes from the Midtown LO.
Once you flip the Midtown LO you discover a two page LO with mixed paper sizes. The 8.5x11 page on the right is adhered to the blue 12x12 paper.
Photo below is a close-up of the 8.5x11 page on the right side. My SIL took that beautiful picture of the subway. It is one of my favorites of the trip. IRL the picture is rich and saturated with color. My pic of a pic did not turn out so well.
