Here's a simple DL invitation from 1982. I seem to recall that I used to knock out stuff like this almost on a daily basis. And I was lucky to be able to get away with such a simple concept on this one.
But look how 1980s it looks (at least to me). The white border for a start. It seems that everying I did in the early eighties had a 5mm white border. Maybe it was just fashion. Or maybe it was because printers would charge (a lot) extra for anything that bled off the page. Why? Because they could, probably.
And then there's the typography. You wouldn't think that one word could say so much. But only to a typographer.
