**Notes**:
  * Early rectangular decals did not say Columbus at the bottom.
  * Decals after 1972 were a red dove on gold foil.
  * Decals after 1975 had a white dove on a red background.
  * Decals after 1978 had a fatter dove with no name.
  * Decals after 1984 often had the tubeset name.
  * Decals after 1988 put Columbus at the top with a funky background.
  * Starting the 1990s, decals started using some English, as in "differential shape butted."
  * Decals after this use the ® symbol, funky backgrounds, Columbus at the top and white dove.  Other colors and words will change depending on the tubset.  Dating these requires a set of Columbus catalogs.
