Happy Birthday to Rainbow from Smash-girl

This was the very first Rainbow envelope to arrive - and it's *smashing.*

It is a long strip of paper, folded three times and adhered with a luxuriously large gold seal. It came through the mail very nicely.

A stealworthy idea, fur shur.

The back, with gold seal.

Starting to unfurl.

Half way open.

All the way open.
