I love old postcards - particularly the ones that are hand-tinted and feature glamourous ladies or cherubic children. These are a couple I bought recently; I think they are gorgeous and far nicer than the sort of greeting cards we send today.
I often wonder about modern items we have now; and whether they will make nice vintage things in the future. I don't really think so; in fact, I'd be suprised if very much of it actually survives as we are such a throw-away society these days. Oh dear - turning into a grumpy old woman here! Must go and eat some of hubby's birthday cake and cheer myself up.
