The story

Behind the P2P E-Cash Paper, Oct 31, 2008 tee

Some shirts tell you what to think. This one repeats a subject line instead. Below an orange curbside mailbox with its flag raised, three white lines copy the subject of the email that first announced the Bitcoin white paper, along with its date.

The Bitcoin white paper was announced by email to The Cryptography Mailing List on Friday, October 31, 2008, which was Halloween. The email header reads 14:10 Eastern time, and its subject line was Bitcoin P2P e-cash paper. This shirt repeats those words beside a mailbox with its flag up. It is a nod to the email, not an endorsement from anyone on that list, and it is an independent tribute with no affiliation to any person or company.

Wear it on October 31 for a quiet history joke that only the bitcoin crowd catches right away. The 18th anniversary of the paper falls on Saturday, October 31, 2026, which makes it a ready-made talking point for a reading group or meetup. Let people read the small date first, then point at the mailbox and explain.

Questions

About this design

Why does the shirt copy an email subject line?

Because the subject line is the most direct thing the shirt can quote. The paper was first sent to a cryptography mailing list under the subject Bitcoin P2P e-cash paper, so the tee uses those exact words instead of a made-up slogan. The mailbox is only a picture to hold the words, and the design adds no claims about what followed.

Is this shirt an official product connected to the email?

No. It is an independent fan tribute that echoes a public email from 2008. It is not connected to, sponsored by or endorsed by any person, company or mailing list. The white paper is available to read in full on bitcoin.org if you want the original text.

Can I wear this on Halloween if I do not dress up?

Yes. This is a shirt for people who like their Halloween quiet. October 31, 2008 was a Friday and Halloween, which gives the tee its date. The design is printed to order, so allow a few business days for printing before the day you have in mind.
