#295, 2c Pan American issue. Top left corner plate no.1092 and full arrow block of twelve. With long strings of printer's initials in both carmine and black with the black string extending completely across the selvage.
Large reversed "2c" in carmine and black in top left corner selvage. Reverse black "6" for printing sequence (plate production).AR with "WEC" crossed out next to plate number. While there are plenty of 2c plate blocks of six on the market, there are very few plate blocks of 12 with these marginal markings. In my 25 years as a full time professional philatelist, I have never seen one with the "AR" and the "WEC" crossed out. John Meek wrote in the December 1979 issue of "The Bureau Specialist" that he has a plate single in his collection with a string of printer's initials with "WEC" nine times and only one "WFC".
Meek wrote "No where else in the string is a "WFC" so one has to conclude the plate printer accidentally picked up the "F" punch or is it just a poorly entered "E? The main thing to be learned here is that one has to take care in deciding how many printers actually put their initials on a plate.I doubt there was a plate printer "WFC" as I once entered in my list. According to Max Johl, the sheet margins of the Pan-American stamps contained rows of apparently meaningless initials.
He stales that each time the plate was taken from the vault for printing, the Bureau required, as a check system, each workman to impress his initials on the plate margin before putting the plate to press. According to the Durland Standard Plate Number Catalog, 12 different plate numbers were used for the frame (carmine) and 36 for the vignette (black). 1092 is the second frame plate used.
