The restoration is very good.
Now we can see the baby has a flowery frock and the photo creases are gone.
If Granny Mc Laughlin/ Mcnamee died in 1921 then I do not think this photo is of her, sepia or not.
The lady,s dress is not from before the 1920,s.
I saw such dresses in the 40,s
Is that a white belt around the waist?
Do you have a photo of Granny McL. that could be compared with this one?
