Postage stamp silhouettes: Fairly certain I was signed up for a mail order stamp collection at my Dad's... If yes, this might be a good way to go with them. (Now, as for the mail order quarter collection...)
This feeds into my affinity for postcards, collage and postage. The art of letter writing and postcards is on it's way out with the digital age; but I still get charmed by it and would love to see it revived.
