The Netherlands and Belgium have a pre-marriage requirement to formally register to marry. Back in the 1800s, engaged couples not only had to register, but they had to announce their intention publicly through cards.
Today, the process is called “Ondertrauw”, but the spelling back in the 1800s had a “d” added to the end of the word.
The six larger cards have dates of 1897, 1898, 1899, and three from 1901.
Two of the announcement cards are in fold out format, dated 1895 and 1902.
The four smaller cards are dated 1881 (2), 1885, and 1903.
I purchased these twelve rare cards from an estate near Holland, Michigan, which has a strong Dutch heritage.
I’ve never seen anything like these cards. Fortunately, they survived all these years.
