In most hotels, these seem to be appearing in catalogue at least 2 or 3 times a year, so they’re rare, but not hard to get your hands on.
Rare
These are either really rare, or only available in some hotels, like the English of Finnish spaking hotels, related to their country.
Regular
In most hotels, these are the always available posters. Don’t count on it though. Dutch hotel, for instance, pulled the skyline by night poster by surprise and it’s a rare item now. Likewise, the ‘Tree’ poster is a rare item in some hotels.
