Unfortunately, the CafePress calendar format is fixed - no back cover.

However, your question has made me decide to reveal a little surprise I was planning. I was planning to create a couple different layouts.

There is a single page yearly calendar which is 11x17", and also an oversized 12 month calendar which each page is 11x17" (as opposed to the 8.5x11 for the standard calendar). There is also a vertical format 12 month calendar which is which has an 11x11" photo area.

With all of that said, the non-standard calendars will be difficult to make, because they require VERY high resolution images. I'm hoping that I can make one of each style available, but that will depend on the resolution and the layout of the images.

So hopefully there will be 4 calendar styles available. I'm not guaranteeing that right now, but I'll do my best. Like I said above, it is largely dependent on the resolution of the images people send me.
