Unused, gently aging Mathews Post Card Service item, no reference number.  Made in U.S.A., with all wording in English, we went to Google to try to learn if this card had ever been for sale in Brazil.  The answer to that is not clear.  Mathews distributed postcards of many countries, which are easily scouted out in those respective countries online, but we’ve run out of time and energy to ask.  Grade: 1
