Digital BW, The Print

I have a group of 8.5x11 digital prints that I'd like to present in a bound 
portfolio/presentation book. However, all of the prints are "landscape" 
format, and all of the presentation books I've found are in the traditional 
"portrait" format (i.e. binding on the long dimension). I prefer the idea of 
seeing the prints side-by-side instead on one over the other.

Does anyone know of a company that makes/sells "landscape" format portfolio 
books? My current favorite (in "portrait" format) is the Prat 133 Siva model, 
black bound leather w/ crystal pages.

Sorry if this is a bit OT, but I figured most people here have a portfolio of 
one kind or another. Thanks.
