The U.S. Regular Issues of 1922–31 were a series of 27 U.S. postage stamps issued for general everyday use by the U.S. Post office. Unlike the definitives previously in use, which presented only the Washington or Franklin images, each of these definitive stamps illustrated a different president or other subject relevant to the nation. Washington and Franklin were confined to a single denomination.

The Presidential Issue, nicknamed the "Prexies" by collectors, was the series of 32 definitive postage stamps issued in the United States in 1938 that featured all 29 U.S. presidents who were in office between 1789 and 1928, from George Washington to Calvin Coolidge.

These two historical covers, mailed by stamp collector Olga Parreiter of Chicago, include examples from both the United States Regular Issues and the Presidential Issues, the Prexies.

The first cover has 15 examples of the stamps. The second, 12 including the dollar denominations. The total cost of the first was On dollar and one half cent. The cost of the second, 10 dollars and ten cents. The paid special delivery fee on the second cover, 20 cents. The total, 11 dollars, thirty and one half cent.

The covers, mailed from Chicago, Illinois to Berlin, Germany on June 16th, 1939, were sent to Leo Wojakowski two and one half months before Hitler's invasion of Poland on September 1, 1939, the date of the beginning of the Second World War.

It is believed that the airmail cover contained funds for Mr.Wojakowski to provide for his escape from Germany.

The consensus among mid-south philatelists is that Leo Wojakowski, most likely of Polish descent, escaped the tyranny of Nazi Germany thanks to these two remarkable covers. As they were discoverd in the United States, I believe that he made safe passage to our shores, thank God.

I own them.
