Get Out That Postmark Notebook!

It is time to get out that postmark notebook! Look at the postmark below. The postmark does have some things that are interesting. There are seven lines and two corners in the bottom moon. Unfortunately, determining the line count in the top moon is impossible. The top and bottom of the postmark are separated by six-pointed stars. Both postmarks have a broken lower horizontal line on the right side. Even with this much information, without the line count from the top moon, it is impossible to determine the postmark type. None of the handstamp types listed in the VPS Postmark notebook have 7 bottom moon lines with two six-pointed start separators show a broken horizontal line. Perhaps postmark-type usage dates would narrow the list of possible types down a bit. It is probably best to leave a declaration of the postmark type unresolved at this time.
