Unknown: Possibly c. 1900 because the paper is fairweather limited letterhead which is from around the 1900s. It is possible the drawing was done later though.
c. 1900: This piece is probably from her visits to Churchville, and shows the possible influence of Elizabeth McGillivray Knowles meaning it was probably done in the first decade of the 20th century.
c.1920: This piece is done in the style of Ingle's illustrative work which she mostly did in the 1920s and 30s. This piece is in a leaflet containing pieces 0473-0478.
c. 1930: The reverse side of this piece has a sketch from Santa Monica, a trip that Ingle took in 1928, so it's quite possible that this piece was done around the same time.
c. 1920: This is one of Ingle's illustrations which she mostly did in the 1920s and 30s. This drawing might have connections to the J. E. Laughlin studio.
Unkown: The face of the girl looks earlier and the reverse side houses a drawing from earlier, but the landscape is dated 1945 though it's possible they were done at different times.
c. 1910: Based on the apparent age of the most likely subject, her niece Dorothy. Though it may be later because a drawing on the reverse side is dated 1945.
c. 1900: Based on stylistic similarities to other pieces and the apparent age of the most likely subject, Rachel Burton (one of Ingle's Churchville relations).
