The Universal Standard Calendar
“The Universal Standard Calendar.”—There has come to our table a calendar for any month in any year in either Julian or Gregorian time (Old Style or New Style), for 2,800 years or any multiple thereof, B.C. or A.D., indefinitely. It is not complicated, a few minutes study gives one an understanding of its wonderful possibilities. It makes possible a quick, accurate, and convenient reference to any date by the student, historian, teacher, or commercial man; and it is just as good for a monthly calendar. You can easily adjust it by means of a revolving disk, and set it for the month as easily as you can tear off a leaf. And it contains, besides, much accurate information. It is mounted on heavy card-board, is neat and attractive. Price, 35 cents. Address the inventor and publisher, H. H. Perry, Oakland, Cal.
