So pleased - I just had an email from Rebecca Guyver to say that my mail art, posted on 22nd February, in San Francisco, had arrived safely in Suffolk, UK. I'd posted the original artwork without an envelope as I'd wanted the postal stamp / franking to become part of the mail art but had wondered about damage or indeed theft. My faith in the postal system is restored ... and I'll shortly do another further mail art piece, this time posted in Doha, Qatar.
