Who is Laura?

Here is Laura:

I found her in a basket of photos at an antique mall a couple of weeks ago. I am distressed that she was left without her true family. Therefore, I have adopted her.

I think this is a school picture. It appears to be from the mid-1920s and Laura did sign "Sincerely, Laura". Who is she and who did she give this portrait to?

She is being worked in to art projects. Laura will always have a home.

I was at the Salvation Army today. There was a set of Currier and Ives glasses.

I couldn't get all seven glasses. I purchased the one with a coupon inside.
