I've come from an event about free software where we spreaded, amongst other things, a good ammount of FSFE materials (flyers, stickers, et cetera). It was easy to notice that the most wanted item was the "Hacking for freedom" sticker. I just noticed that the sticker is, however, no longer available, neither at https://fsfe.org/contribute/spreadtheword.en.html nor even at https://fsfe.org/contribute/promotion-materials-archive.en.html . I'm not sure if this is some kind of oversight or on purpose, but I thought I should right to you in either case, because if this particular sticker is as popular as it was in this particular event, then I'm guessing you should probably think about keeping it :-)
