In Denmark when letters were not handed in at the post office, they could be placed in collection boxes at railway stations, bus stations, and on ships. For many years such mail was given an undated handstamp marking containing a figure of a posthorn topped with a crown, and the name of the town where the mail was collected. Then a properly dated transit post office mark was applied.

Posthorn cancels were normally placed alongside the postage and the TPO mark was used to cancel the stamps. Occasionally stamps and covers are found where the opposite was the case. Posthorn cancels are a popular area for collectors and some scarcer ones have achieved rather high values from retail and auction sources.

This priced catalog of the crowned posthorn cancels contains a great deal of information for collectors. There are various types of the markings depending on the location of the town name within the circular stamp. The listings are alphabetical by town name. Each entry includes a catalog number, the type varieties, the train route, color of the cancel, earliest and latest known use, and value on piece or entire cover. Philatelic or post-period of use marks are of considerably less value. There is also mention of the dated town cancels that normally appear with each posthorn mark.

Illustrations throughout the catalog are in black and white for the markings and in full color when an entire cover is shown. An index indicates geographical location of the town mark in Denmark.

This catalog goes beyond the posthorn markings of train station collection boxes to include other kinds of marks on items placed in boxes and then marked "Ladepost" and "Togpost." Bus station collection box mail received "Rutebilbrev" markings both circular and straight line, and these are cataloged and illustrated as well.

Lastly an important appendix lists the markings frequently applied to ship mail to indicate its origin, such as Fra Aalborg, Fra Færøerne, Fra Sverige, etc. These markings are also priced and illustrated. A list of literature sources concludes this monograph.

For the collection of unusual postal markings of Denmark, this catalog is a must-have. The layout and illustrations are excellent.
