Here I have taken elements from the diagram and spaced them evenly. I have used all the key events, and although I like the idea of picking them out of the diagram they don't work well within this format because they are too small.

This is the original diagram with all the type taken off it so it's just all the symbols/lines. I quite like it visually but it does not work at this scale at all and may be worth exploring at a larger size.

An example of a postcard which takes elements from the original diagram in their original formation. This one shows just the arrow heads, indicating travelling backwards in time.

The two images below were testing out different sizes of format, using different heights between 50mm-100mm. I have now decided to use a height of 85mm. However this may change to keep the same ratio of x:y because I am considering changing the width of the postcards so that they are the same length and the prints are high. This means they will all share one dimension and some consistency will exist.
