I realize that it's far more efficient to use bar codes and inventory scanners now, but they're so impersonal. I myself cannot remember a time when there were price tags used in grocery stores such as the ones pictured on the left - I'm guessing these little guys pre-date me by about 15-20 years (I was born in '68). In my childhood, it was either those square-ish adhesive price tags (like the ones picutred in my Lo-Fi collage, below) or the inked prices on the bottom of metal spice tins, etc. (like the one below, left).
I love using price tags in my artwork - the first one pictured here, entitled "That's the Price you Pay", is currently in an exhibit at the John Michael Kohler Art Center in Sheboygan, WI. The name of the exhibit is Word Play, and you can see why I titled it what I did. :D The other collages are ATCs that I did for my live trading group. They just lend a great feel to any piece in which they're used.
I enjoy the collecting as much as I enjoy using them in my art - so I can say that I'm doing my very small part to preserve the history of these fun little pieces of nostalgia.
