«Nobody knows who wrote the first letter or when, but we know that 4000 years ago in Ancient Egypt people carried letters by hand over hundreds of kilometres. Very few people could write, called scribes, who wrote letters for everyone else.
In those days you didn’t need a stamp. The first stamp didn’t appear until 1840 and it cost just one penny. Nowadays one of these original stamps cost 375€. Letter writing was so popular in the 1840s that they delivered the post several times a day!
