David,
Both Peter and Cursus are correct in part as Maximum cards are not issued in every country...or rather they probably are, kind of.

In the UK, for example, there are no Official Maximum cards. They are simply called Stamp Cards and show a picture of the Stamp issue to which the stamp is affixed.
Some say they are frowned upon, but although I don't collect them, they are rather nice.
In Israel, Maximum cards are not popular and have not been issued regularly.
The first one listed in my catalogue is the 1981 Trees of the Holyland issue. I have never seen one.
Before this there were Stamp cards the same as the UK types but without the perforations of the stamp on the card, but with the same design.
Israel also have two other 'cards' which are far more popular although some are hard to find.
Souvenir Leafs are stiff cards similar to Maximum cards but larger to which a stamp or stamps are affixed. The cards are issued in acid free top loading plastic pockets and are very attractive.
There are also special cards sent to Philatelic Service subscribers at the time of the Jewish New Year and/or Pessach. They are like a greetings card, folded, and inside are the Festival stamps and appropriate cancellation. Most are hard to find due to the limited numbers issued.
I will send you an example of each with your FDC's.
