Receive random postcard from our batch of Xmas Postcards - it could be Numberphile, Sixty Symbols, Deep Sky Videos, Unmade Podcast or Periodic Videos.
The blank side will be signed to you from Brady.
Just something fun at Christmas and a different way to support our productions.
NOTE: If you are an upper tier Numberphile or Sixty Symbols Patreon supporter, you may have been sent one of these postcards already!
Postcard will be randomly chosen.
