Alphabet soup is an apt description and thus suitable caption style for this lovely, originally toned CC GSA CAC ROY G BIV (i.e. the mnemonic device to remember the sequential colors of the rainbow: red, orange yellow, green, blue, indigo, violet) Morgan Dollar, the first GSA holdered example we've offered in a looong time.
Captions that didn't make the cut:
We knew we were going with this basic concept, starting with "CC to GSA to NGC to CAC to U.", before migrating to the equation format in the final ad.
In retrospect, that might have been a mistake, since that first version is interesting in my view.
