The 2920 (convertible booklets)

The 2920 is a self adhesive stamp from a convertible booklet of 20 2920a or from a MDI (Minnesota Diversified Industries) booklet of 15 or 30 (BK 226A and BK 227).

This stamp has a big blue 1995 year date and a die cut perforation on two adjacent, three or all four sides 8.8. First day of issue 18 April 1995, printed by Avery-Dennison. The booklet exists with and without divots at the corners, has label with or without bulls-eye die cutting. It exists with several different liner backings: The text
"* Self-Adhesive / Do Not Wet" runs in an 45° or 36° angle from bottom left to top right (Type C45, C36) or inverted from top right to bottom left (Type D45, D36).

The Convertible Booklets:


The pane plate numbers are:
V12211,    V12212,    V12312,    V12321,    V12322,    V12331,    V13322,    V13831,    V13834,    V13836,    V22211,    V23322,    V23422,    V23432,    V23522,    V34743,    V34745,    V36743,    V42556,    V45554,    V56663,    V56665,    V56763,    V57663,    V65976,    V78989   

There are two different backings: "Stamps Worth Saving" and "National Domestic Violence Hotline". As far as I know, the panes of 20 occur with or without divots, the MDI booklets come with divots. To me it seems that the stamps from the panes of 20 can be distinguished from those from the MDI booklets by the sequence of valleys and peaks in the die cut.
The pane stamps start with a valley at the top left corner of the horizontal die cut and end with a valley, the MDI stamps start and end with a peak. All other sides corresponding.
