Alphabet Series: Alphabeta Concertina - Minuscule - Bookalphabeta concertina minuscule is Ron's classic lower caps letter version. It is artwork, typographical experiment and feat of paper engineering. Its gently unfolding letters is in a sense a reply in lower case form to the third, the original cap version published in 1983. All these versions measure 1711 x 3 cms stretching to 3m; printed, cut and creased onto Heritage paper and glued to Heritage Museum board inserted into a pvc tray and sleeve.
