This tote bag is emblazoned with a beautiful seven-way Venn diagram, as seen in our second show "Just For Graphs".

For a Venn diagram to be valid, all possible combinations of regions must be shown. This arrangement of beautiful shapes, designed by Branko Grunbaum, fulfills that criteria with startling symmetry.
