Experiments with designs for flyer/poster for advertising my exhibition.

I have recently been experimenting with designs for advertising posters/poster for my exhibition.  I include the results below.

My preference is for the final one.  I think that it provides all of the required information with a preferred format for the photograph.  The suare format works well allowing for information both below and above.  I have chosen a backgound to colour to tone in with the image without intruding too much.
