Square quarto. (8)ff. Versos show various imperial-to-metric conversions in English/Latin letters, facing their counterparts in Braille at the facing rectos. Scarce, with only two copies in institutional holdings. Scarce, too, as evidence of the provision of diverse reading material by the American federal government. Bound in printed and embossed self-wrappers. Light rubs to corners, else quite crisp and near fine.
