It’s complicated, but actually very simple:

Involved, Socially =
*curated by Michelle Blade
*features 5 artists
*the upcoming exhibition at Triple Base Gallery

This & That International Mail Art Swap =
*curated by Christine Wong Yap
*features 32 artists/artists groups
*a show in the back room at Triple Base Gallery, part of Involved, Socially.

You might think of This & That as a:
*curatorial project
*sub-show
*Little Big Show

Factoids:

The acronym for This & That could be “TnT.” (Thanks Churchill.) Hence the AC/DC theme song suggests itself.
