[Which is the number line] The spelled number line, also used briefly by DAW, was [fortunately] only in use from February to April 1973 The artist is not credited, no visible signature on the artwork Printed in the US The LCCN on the copyright page is for the Holt, Rinehart and Winston hardcover edition.
