The inside dimensions (allowing for the frame)
of the poster frame is 23 x 35. So My plan is
to make (9) separate 8-1/2 x 11 files.

Note on the picture that I have an overlay
which is a grid which I will remove prior to
making the (9) files. Also I had to allow for
a top and bottom border of 1" to make up for
the (3)high 11" prints.

There is either 48 or 50 images here. Every
time I count it is a different number.

More work to do on image sizes and masking.
