1986-87 Transportation Series
In mid-July of 1986, the Postal Service asked the philatelic press to alert collectors to new varieties which would be appearing in the Transportation Series. Since the USPS had stated that formal USPS announcements should not be expected, collectors were simply told, “They (the stamps) will just begin showing up in stocks.”
Omnibus – 1¢: The re-engraved version had a larger numeral “1”, while the central design was made smaller. The “USA” came after the value instead of preceding it, and the cent mark entirely disappeared.
Locomotive – 2¢: In keeping with the 1986 USPS decision to make stamp numerals as large as possible, the numeral “2” was enlarged to twice its original size. The cent sign was eliminated and the “USA” was moved behind the numerical value, changing the “USA 2¢” to “2 USA.”
Stagecoach – 4¢: This revised definitive retained the cent sign and kept the “USA” in front of the denomination. However, the stagecoach design and lettering were made smaller.
