Mouse, Cat, Squirrel: Wonderful 1907 D.B Webber Ink Drawing on Back of Sketchbook Cover

This is one of a bunch of drawings by a D.B Webber of Concord, New Hampshire that I found together in a plastic sleeve digging through the files of a favorite antiquarian bookseller in Maine, all dated 1907--and it really made my day to find them, just my sorts of drawings, and of the sort it feels harder and harder to find. I haven't managed to definitively identify their maker, but there are plenty of records for Webbers in Concord and nearby. I think these pretty much speak for themselves--and of a lively mind, and eye, and hand, for sure! 

9" x 5 3/8", ink on the cream paper covered back of a sketch book cover, as shown. Good condition.
