#WritersCoffeeClub Should a writer have a face shot on their book cover or within their book?

It’s up to them, and/or the publisher.

However, this also ties in with the author’s name on the book. Is a face shot and my full name going to sell more books or is it more appealing to readers if I remain ambiguous? 
Personally, I don’t want to hide who I am. I also find it odd a certain high profile author and TERF uses an ambiguous name and a male pseudonym for her work.
