Pastel 1: Identification Needed

I saw two pastel portraits at a thrift store I frequent. I liked them, but not at 15 dollars each. I rarely spend $10 on any single item at a thrift store, let alone two.

As such, I passed them up. Later in the evening, they crossed my mind again. I decided to research 'antique pastel portrait' on e-Bay and clicked Sold Listings. I was surprised that pictures of dead, unrelated, often unidentified people sell for so much. It seems that, the more colour and background, the more the price-- not necessarily influenced by the quality of the work.

I'm also going to make another post of 'his wife', as I'm calling her. I picked up two of these. LOL. She has a tag with someone's modern, sloppy hand-writing saying who they are, plus the price tag the dealer put on them.

I opened them both up. The man is done on good-quality card-stock, while the woman is done on deteriorating canvas with damage. She had nothing marked on hers, but as you can see, he has a lot of markings.

Anything useful for identification or age? I'm thinking early 1900s?

For those who deal in these, I was wondering if enlisting the help of our college's art-students to touch up some damage would negatively impact value? I am sure they could match up the pastels.

As Pastel is basically a solid version of Oil Paint, I'm putting it in Paintings.

Not sure if photo two is broken on your side also, with the big line through it?
