Erasure, letter by letter

The "Jasper Johns gets plastered" look of these letters is done by layering cut-out letters with polyfilla (gyproc) - each letter erases the one beneath -

A great idea from Liz Davidson's "Helvetica variations" in the letter-a-day project. The rest of her work along this theme is eye-opening -- do have a look at the drilled version, before and after it had a bath.
