about each of them...

Are these sentences correct:

[color=red]1) Of him, we only have a photo.

[color=darkred]2) About each of them, a few books have been written.

[color=indigo]3) Of each of these poems, there are several interpretations.

[color=blue]4) About each of these poems, there are several interpretations.

Gratefully,
Navi.

The same applies to sentences 2 and 4 as to those posted yesterday. ‘About’ does not generally come at the beginning of a sentence.

‘We only have a photo of him,’ is usual, but there are instances when ‘Of him, we only have a photo’ would be appropriate. However, even these would usually be a follow on.
“We have full details of all of the men except Jack, Of him, we only have a photo.”
The same thing occurs in (3) where the usual form would be ‘There are several interpretations of each of these poems’.
