I can't find another copy or even a trace of this book of tongue twisters out there anywhere, so don't think there were a whole lot of cops produced. What a pretty and fun little one it is though, with 16 pages worth of enunciatory challenges, some familiar, others certainly new to me. A great gift, or perfect amusement for cocktail hour.
4 3/4" x 3 1/4". 16 p plus endpapers. Hardback, with some wear/scattered light stains to the cover; overall good condition. "Mildred Whitten" hand-written in pen on the inside cover.
