Artist’s Trading Cards are small, 2.5 x 3.5 inch, works of art that are made and, most importantly, freely traded.
I made this one, at work, in a few minutes. I used a discarded file folder for the stock, the floppy part of an old floppy disk, a part of a page from an outdated phone book, staples, paper clips and envelope sealer as glue.
It is, simply, Office
(There is a bit of scanner glare at the bottom of the floppy; it being shiny material.)
