No one is going to remember us after our deaths if our only merchant contributions to the world are records and t-shirts. We need to get on the level of this Factory Records duct tape:

If you have a suggestion for an item that a)
is practical, and b)
has surface area which allows for high-visibility branding, then please let us know.
Ideas so far include:
tea towel, passport cover/wallet, wall clock and
emery board.
