That's an INVOICE hanging off the corn plant or palm or whatever that is. It reads, among other things, "SSI - SFZero International 761 Oak Street, San Francisco CA" and the address of the college, along with the note "Packing List Only - Not A Bill - Do Not Pay" and "delivery charge: waived" as well as "Grn Rm : "Michael" The way I see it, nothing lends legitimacy to a delivery like a Microsoft Excel invoice template. Nothing is more blandly authoritative that "These belong here."
