Veronica - Eunice postcards

I have hundreds of postcards from Veronica because I have known her for many years. 

In amongst my postcard collection I found one saying “the party has begun” bye with no signature – I have no idea who sent it.

Another postcard said “so far things are idyllic but it is only day one” signed Anthony – who is he?

A card from Adelaide in 1997 was love from Rita – who on earth is she?

Veronica may know who they are, I shall ask her.
