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.
