What informed music teacher in her right mind would purchase this book of music activities for kids? Who knows? - the materials inside the book might actually be worthwhile. But the child pictured on the cover has clearly never had a lesson in her life. If the cover had so little effort put into it, why would anyone be confident that the content could be any better?
This type of thing is a pet peeve of mine. My alma mater had a photo advertisement gracing magazines for years featuring a student (not a violin major) who played fiddle just for fun. There she was, her violin tucked under her chin rather than held between her jaw and collarbone, the instrument sliding downwards towards her stomach, her bow held incorrectly... no prospective violinist would give the school a second thought upon seeing that picture!
