HELP w/ARTIST'S NAME ON 4 RUSSIAN SHIP PRINTS?

I met a guy who was emptying out a storage unit & selling things at great prices to meet his final day deadline to be out. I bought a beautiful nude oil on canvas, a cool Edwardian woman's face door knocker & a couple of other pieces.

When I was packing up, he gave me 4-5 old frames for free & these 4 russian steam ship(?) prints for $20 total! They were professionally framed & I'm wondering if they have any value?
Also who the artist is (same for all 4 but I can't make it out)
And how old these might be? (the ships are from the 1920's)

Thanks all; I appreciate your help.

 

Here are last two - same artist signature:

 

They're Greek, not Russian. Artist's name is Α. Μιχάνος, which would transliterate as A. Michanos, but I'm not finding anything in a quick search. One of the ships is named King Constantine. IM Translator is making Hyperaction out of ΎΠΕΡΟΚΕΟΝΙΟΝ, but maybe more like supertanker?

 

Thank you - hard to believe the artist isn't known; I think he did a great job on the ships!

 

they are indeed lovely boats !!

 

Hi Komokwa,
They are NOT boats. Ships have boats. Submarines are called boats since they do not have boats. Are you confused???

Hi,
In the U S Navy ships have boats

Think ΎΠΕΡΟΚΕΟΝΙΟΝ may mean 'steamer'. The Ύ/Κ on a couple would be an abbreviation.
