I can see 1934 not 1924. The top of the '3' is visible. Part of it is missing, but still a 3.
It is undeniably, and with 100% certainty, that it is a "2" and not a "3". Thus the year is (without question) 1924. The signature in question matches up perfectly with a 1924 time frame signature. His 1934 signature, while similar, looks nothing like this exemplar.
