Gum Breakers on Rotary Printings
Franklin O. Davis feels that the various types of gum breakers used at the Bureau to keep stamps from rolling up after issue, are of considerable interest and I agree, except that I haven't found the time to keep up with them, beyond noting that there have been several varieties used in the spacing of these breakers. He reports that he recently acquired a block of the current 20¢ Special Delivery stamps with breakers in both horizontal and vertical directions on the same block. This is something unusual that I haven't seen and if deliberate and not the result of accident, it means extra processing work for the Bureau since the sheets must be put through the rollers twice.
