Featured Maritime painting ?

Wanted some input on likely age and style. What I know is it's gouache on paper measuring 15 x 22 inches (w/o frame). It was purchased at Christie's London in 1980. Not signed on front - might pull it from frame. Reminds me of the 19th century nautical renderings of ships in trouble, but the colors are a bit unusual. Seems that framing was done 40 years ago.

 

eem ???? Nevermind. I see it has been corrected.

 

I like it and the palette is terrific. I’d definitely pull it and check the back. First word that comes to mind for me is “illustrative”.

 

Looks like a military frigate???? The blue ocean is "off" to my way of thinking, though, for those stormy skies!! What are those 2 vertical black things?? Not 'stacks' I hope....if so, never saw any looking like them....BTWDIK!!!!

I'd definitely pull & see what it says....what makes you think the frame was done 40 years ago....or is that based on Christie's sale in 1980?!

 

Ocean looks purple to me.

 

Yes, they'e stacks, it's a transitional steam/sail ship as was seen 1840-90... the hull does look military.

 

OK, thanks!!!

 

I think this would have come from Christie's S. Ken sales, auctions that were pretty much like backroom sales in provincial towns.
It's OK, but that's about it IMO

 

Looks like it is ironclad..... https://www.google.com/search?q=iro...UQQ80KHTQZCAkQ_AUoAnoECBgQBA&biw=1266&bih=726

 

I googled "ironclad frigate painting" and clicked Images. You can see many examples. They all seem to have two stacks instead of one so this may be the artist's imagination.
