Curious Post

Curious Post is a monthly envelope from Cohen's Curiosity Shop built around a new original digital illustration. Each edition includes a signed print of that artwork, stickers tied to the theme, a note explaining where the idea came from, a fill-in-the-blank activity and a decoder puzzle that hints at next month's title. The theme changes every month and stays a surprise until it lands.

It costs $15 a month and renews until cancelled. Sign up by the 15th to get that month's envelope; sign-ups close after the 15th and reopen on the 1st. Envelopes go out around the 20th by USPS First-Class without tracking, US addresses only.

Made for people who like their happy mail a little odd.
