ÁÉÍÓÚ áéíóú

fiche se,

Again, I still haven't found the items I had planned to throw out next, so instead I just grabbed the first box marked 'Opened' and started into that. Some items are from quite a while ago.
ENVELOPE
This long envelope looks very 'legal' and might have once contained important documents at one time. It is not possible to read the postmark, but the address is 1970 or later.

LABEL
The label SOCIAL ARCHIVE refers to the other collection I have been making over a number of years. This collection is of junk-mail and similar advertising or promotional materials which are mostly unsolicited and do not have a personal connection as such.
NOTE
This is dated January 1982, and seems to refer to the early days of my husband's work in a local school.
PAPER
This is a statement to the members of Tallaght Ladies' Club telling them what their income and expenditure was for the year ending December 1974.
