This is for a New Old Stock vintage ca 1970s bumper sticker from Ski's (aka, Ski-Cal De-Sign) which reads "E-Z Duz It" with a thumb's up graphic and a black background. 11" x 3".  This is a prism/sort of hologram design, so reflects light with a variety of colors - but it is basically silver.  If the photo shows other colors, it is from light reflection.
