Thrift store find - Frank Auerbach painting?

I found this cool painting at a thrift store yesterday - there's no signature I can see on the front but I can make out Frank on the top back of canvas, with a unreadable 2nd name below that.
I took a photo & did a image search on my phone & Frank Auerbach paintings came up - Could this be by Frank Auerbach?
Thank you for any help!

 

With Google Lens I get many paintings, but not one Auerbach
And this is his signature

not one matching letter style.
But I'm no expert, so let's see what the real connaisseurs have to say
(and is it Frank, or is it Frantz?)

 

As with many artists, he was copied. Perhaps this site could get you started:

Nope

 

I like your painting JM but don't think it's Auerbach. I also like Frank Auerbach,one of David Bowie's favorite painters.Same general era as Lucien Freud & Francis Bacon.

 

Frank Moore?

 

I haven't heard the name David Bowie in a long time - one of the Kings of rock n roll!

 

Do they have his signature ? On back?
Thank you - definitely a maybe!

 

I sent a note & pics to the Berkley museum that came up when searching Frank Moore asking if it was by him; I'll let you know.
ps - I didn't know he was in a wheelchair & painted with a brush attached to his head?!

 

It looks like the artist had fun making this. It has an appeal to it. Good texture, and just when you think the mixing strokes are a mess, a highlight pops through.

 

I hadn't heard of his name before, but in the second line I read 'Mor', so I googled for "frank mor painting" and, of course, google gives results with words you didn't ask for, but in this case it was a (possible) positive thing, as his work does indeed look similar. There are also Frank Moore paintings with a different style, but that another FM.
I couldn't find any signatures, and that Mor, or whatever it is, on your painting doesn't really look like Moore, and what I read as an R is different from the R in Frank, but if I had to sign my name with a brush attached to my head, I wouldn't do a better job.
