1936 Boxing Autograph - Help Needed

[ATP]

Anyone here recognize either of these signatures? I love a good mystery but these two are bugging me. They were kept with autographs obtained in 1936, and in the section of mostly other boxers (though there were a couple baseball there as well in that section from 1936). Some boxers were very famous like Jack Johnson and Sixto Escobar, some very obscure like Irish Eddie Brink and Solly Seeman. I keep coming up with seeing something to the effect of S.G. Libowretcry and Len Fehlomsen, neither of which of course are a real person. Any insight is appreciated, thank you in advcne.

Might be Lew Feldman. Definitely the right era.

Yeah, I would say Lew Feldman on the 2nd one. Can't make sense of the first one myself.

Thanks Adam and Dave, you are right it likely is Lew Feldman. Makes sense too because he was a New York boxer and that is where it was signed. I will keep staring at the other one more and see if I can figure it out. Thanks again for the help.
