A fine example of the hurry-up aspect of my hypothesis - carries over into affixing stamps to the Poster. On the Mineral Heritage issue - if not watching carefully - the stamps can be affixed incorrectly. The Smithsonian cancel on this issue bares this out as illustrated below.

Not only was the cancel placed hurriedly - but the stamps were place in a mis-oriented position. Hurrying along - the next cancel item involves a Smithsonian cancel on a Souvenir Page - 6.3-cent Precancel. Here is a nice item in that three stamps were used. However, there appears to have been little thought on this issue. Coils with a line should appear in center - which means the line should be between a pair or foursome - but never on a threesome. And what about a strip of five? On this debate, it was finally settled upon using 4 when a line only appears. However, on the early transportation coils which had both line and plate number, it was decided to collect these in strips of five - with the plate number on the middle stamp and the line to the immediate left or right. This logic didn't come to fruition until the transportation coils were released, starting in 1981. Gerald Blankenship has a strip of 5 that appeared on a recent Journal cover and is a very nice item that adheres to this philosophy - AND IS SMITHSONIAN CANCELED!
