Who Am I?

Do you know this man? Or perhaps you know this lovely girl with her bicycle?

This mysterious item has a series of six photographs printed on fabric and bound together on a wooden holder. Based on clothing and hairstyle the photos seem to be from different time periods. Are they all different people?  Did one of those children grow into that lovely young lady?  Are they all family?  Why was this made?  When?

This came to us from a woman named Rose Hogan as part of an archive from families named Hogan and Roskopf but nothing is known about this item or the people featured. 

The family included teachers and attourneys and has connections to Iowa City, Galva Clearfield, Diagonal, Denison, Teril, Dunlap and Estherville in Iowa, as well as Chambers County in Texas, and Foxhome, Minnesota.

If these faces look familiar, please help us identify them and solve the mystery.
