I propose...

...for the next show at the triangle space, having two title labels placed on the wall in close proximity to each other. Following the labelling style and convention used by the other exhibitors (assume the label is placed to the left of the work), the label on the left will have the following text on it: 

That is That.

The label on the right will have the following text on it:

This is This.
