Charming Group of 19th C. Schoolgirl Watercolors of Fruits - Sold as a Set

I'd love to see these wonderful little watercolors hanging near a bowl of stonefruit versions of the same (though the cucumber, perhaps the most charming of all, might be a bit of a challenge to match!) Certainly all done by the same person, who signed one of the plums -- it looks to read "Painted by __ (?) E. Bailey"  with the first name perhaps being Kate, which of course makes me like these all the more:) A few feature what appears to be crayon in addition to watercolor and pencil, including the pear, which was done on a lighter weight, gridded paper.

Pear measures 5 7/16" x 3 7/8". Small plum measures 2 7/8" x 2 1/4". The paper of the banana shows some staining; otherwise they are in very good condition. Sold as a set.
