Dear IETF 91 Attendee, Twenty-five years ago, the IETF met in Honolulu for IETF 15. This was long before the days of hosts and sponsors and thus long before there were any official T-shirts for attendees. A small group of IETFers got together and decided that it would be fun to create a T-shirt. The now-famous "Nerds in Paradise" imprint was designed by Julia Topolcic and became, as far as we know, the first IETF shirt ever. It was printed locally in Honolulu and distributed to those who had signed up for it. This is what the shirt looked like: http://www.blkk.com/_Media/img_4721-2.jpeg To commemorate IETF 15 and that T-shirt, we are planning to produce a Version 2.0 in the same ad hoc fashion, based closely on the original design. The cost per T-shirt will about US $ 15.00, priced to offset the cost of this excercise. The final price will depend on how many shirts we order. If there are surplus funds, we will donate them to the Open Internet Endowment: http://www.internetsociety.org/articles/open-internet-endowment-0 If you wish to pre-order, please let us know what size and how many you want by 23:59:00 UTC on October 22, 2014.* Available sizes are: S, M, L, XL, XXL, XXXL. Send your order to: nerds@xxxxxxxx. You will be required to pay in CASH when collecting your shirt in Honolulu. No mail orders available, sorry. Bob Hinden Joel A. Jaeggli Ole J.
