The loan? 1929. Asking for Your help.

[Vadim65]

Good day to all forum users! Got two sketches with the signature completely unknown to me Gamaleya. Lived, apparently, in Estonia, because behind red pencil inscription made in Estonian means "Pechora monastery" or someone then attributed? Back they are numbered(numbers 9 and 10). Does that was the order, say, from the monastery? Not if You've heard somewhere about this artist? If so, I would ask You to share information. There is nothing like the Internet, is not found. Relative artistic merit, too, would be glad to hear Your opinions.
Thanks in advance to everyone who responds.
With best regards, Vadim.
