Pretty sure this is the earliest non-hand-written copy of the 16th note GRID by Tom Float. Before posting this I messaged Robb Sirat (BD section leader '84, '85 and all-around amazing guy!). Robb said the first copy Float created was on a typewriter. In fact, he originally created this and the Triplet Accent Grid 4-2-1 the same way - on a typewriter. This copy is from '86, but the grids were being taught by Float to his drumlines as early as 1982. Both are still widely used in the drumline world today.
