The design for these enamel pins shows an original calligram of a migrant bird (the Sea Tern) embedded with the letters S and T. The letters stand for Sign Traveller. Two limited editions of 25 each were produced, a silver plated, more understated version and a chrome plated shinier series.
The illustration was executed in vectors to ensure a precise result. Each pin comes in a handmade envelope which is embossed with the design and signed.
The thick envelope protects the collectible. Each one is embossed by hand.
As the pins are 42 x 27 mm they are produced with a double fixture.
