At the end of the 19th century, an advertisement was posted in a famous English newspaper:

"A 20-year-old girl from a good family, with a fortune of £2 million, wants to meet a normal young man for marriage."

Within a short period of time, more than 30,000 letters from eager brides from all over the world were sent to the email address indicated in the announcement. But, unfortunately, nobody got neither the hand nor the heart of the mysterious bride.

After all, the tempting chosen woman turned out to be... two entrepreneurial English philatelists, who in one move multiplied their collection of postal stamps. This case is considered to be the largest mass replenishment of the brand collection in the history of the Philadelphia.
