Keywords: stamp errors, stamp errors, EFO, Mosher, 1978 U.S. Roses Book Stamp Research Project, Scott 1737, Green EL markings in selvage, "coarse" engraving, registered block tagging. Red EE markings in selvage, "coarse" engraving, registered block tagging. Red EE markings in selvage, "fine" engraving, registered block tagging. Totally imperforate, "coarse" red selvage markings. Cluster of ten missing perf holes, "coarse" green selvage markings. Vertically misperfed, 16mm to the right, "coarse" red selvage markings. Vertically misperfed, ? mm to the left, ? selvage markings (what maximum perf offset can readers report? Can you send me a photocopy, or sell/trade me a pane?) Dark olive-green color throughout the pane stamps including "coarse" selvage markings (normally green design areas only). Olive-green upper four stamp designs and "coarse" selvage markings. Lower four stamps are normal light-green color. Severely underinked green design .areas in the top two stamps, "coarse" red selvage markings. Underinked "coarse" green cross-register-line (CRL) in selvage. Short, underinked "coarse" red length-register-mark (LRM) in selvage. Completely untagged error, "fine" red selvage markings. Block tagging shifted one-half stamp horizontally, "coarse" green selvaqe markings. Overinked "coarse" green CRL in selvage and a vertical color smear to the left of or on both sides of the green LRM. Short (underinked) LL leaf cluster stem on some stamps, "coarse" red selvage markings. As indicated in the foregoing list, this issue comes in two distinctly different selvage mark engraving patterns. The first pattern that was issued contains fewer, thicker vertically engraved lines in the CRL (about 4.4 lines per mm). This is the "coarse" pattern also found in the selvage markings of the Scott No. 1623 a/c dollar booklet panes. This "coarse" engraving pattern has been found in both the red and green selvage colors. The second pattern contains more, thinner vertically engraved lines in the CRL (about 6.6 lines per mm). This is the "fine" pattern also found in the selvage markings of the Scott No. 1948a "C" stamp booklet panes. I have only seen the "fine" engraving pattern in the red selvage color on the roses issue and it may not exist in green. Has any reader found a green one? The roses book stamps are certainly a very interesting issue because of their multitude of EFO varieties that have already surfaced. The Type 1 totally imperforate pane is a real EFO gem and there may only.be two such panes in collector's hands!
