Could Aivazovsky subscribe so?

Dear connoisseurs !

Here is an example of the proposed one antique salon Aivazovsky, where the signature is in doubt. Painting issued as 1850 -60s , the motive - no marina .
And such speculation : could unreasonable holder works for more " credibility " to take da maestro himself to sign ? She - a red-brown color .
