Well, I know that it is an strange one (and no-trains related), but I need help about the 'no ads' or 'no junk mail' sticker that some people in the U.S. put on their 'snail-mail' mailboxes to avoid unsolicited ads. Are there an standard model of these stickers in the U.S.? Or they are 'free-lance' designs? I have asked to the US Postal Service, but without answer (maybe they think that I'm nuts or so ) A friend of mine is an sticker collector (some people choose to collect some things... being able to collect TRAINS... ), and we argued about these stickers in the U.S. (here in Spain, we don't have -still- any law about the junk mail, and the advertisers can flood freely your mailbox in spite of how many stickers you put on it ) I have not been able to find in the net any image of these stickers, so maybe you can 'light' a bit that. Thanks friends!
