Medium: photography 

That series of photographs could be shown on a wall either in one line of 10 photos or two lines of 5 photos.  
In case of a narrower space or a smaller wall space, we could use nine photos of the series to create three lines.
The ideal dimension for each work would be 18"x12"or 45¾cm x 30½cm  The work could be either presented with frames or just by using magnets.
