In 1936, the Third Reich released the Modern Buildings issues in booklet form, or Markenheftchen (MH). The booklets (MH 43) consist of the following panes, or Heftchenblättern (H-Bl.):
- One H-Bl. 107 consisting of MiNr. 636 (x5) and MiNr. 637 (x5)
- One H-Bl. 108 consisting of MiNr. 634 (x4), MiNr. 639 (x5), and text field (x1)
The panes are separated by a blank interleave.
The booklets and panes have numerous varieties, depending on the length of the staple and the placement of printing marks within the pane margins.
