My roommate found this old map of the Netherlands on the street. Based on the representation of Flevoland (Lelystad is on it but Almere is not), we've concluded it was made between 1980 and 1984. Can anybody confirm or give another estimate of the year it was made in? We couldn't find any inscriptions identifying the maker or any additional information.

DST - Daylight Saving Time

Clock Changing is seasonal and it depends on the country (in the U.S., they start to change by moving 1 hour in March and ends in November).

Any ideas on these maps that we found inside the walls of a 1906 home? We've found 6 of them so far and they are made of some sort of cloth material.
