14 April 19

Two special events to note: (1) Saturday marked the birthday of not-very-famous American crypotologist Herbert Osborne Yardley (1889-1958), and (2) today marks the beginning of my twelfth year for this tie blog! This is entry #2249.  For entry #1, on 13 April 08, I wore this spy code tie to honor Yardley's birthday. I'm sure you can see the highlighted letters among the rest of the letters and numbers.
