These are four vintage gospel or church sheet music booklets, and each contains one song.  There are two purple covered ones that are the same, and they contain three numbered pages, and were published in 1972 by Lillenas Publishing Co., with the song title "Jesus, the Hope".  The green covered booklet contains nine numbered pages, was published in 1964 and 1971 by Lillenas Publishing Co., and the song title is "Let Me Touch Him".  The red booklet contains four numbered pages, and this edition was published in 1975 also by Lillenas Publishing Co., with the song title " 'Tis Marvelous and Wonderful".  They each measure about 10" by 6 3/4", and all are in gently used vintage condition.  Thank you for looking.
