You may not be reading that WWII draft card properly. I think that the Emergency Revenue Division was/is part of the NYC Department of Finance, and the comment of "License" before it may just mean that he is legally licensed by the department- with the license number being M241033. That 50 Lafayette Street is likely his business address (storefront/office?), as I doubt the person who filled out the form would have felt it necessary to add the address of the government licensing administration. That other coding seems to involve something called an Alien Registration Number (4422387). I do not know much about these myself, but a quick online search suggests that there were forms that were filled out at the time and that these forms are archived on microfilm somewhere.
As Anker does not show up in the online NYC deaths database that runs through 1948, it is likely that he died after this time (though not definite as the database is missing records and contains some inaccurate transcriptions). If you really want the death record, then you can read up on ordering them from the NYC Department of Health's website, but they are going to hit you with a charge for each year you want searched (assuming you even meet their criteria for releasing the records and their payment requirements). They likely won't give you the cause of death regardless. The certificate will note the place of burial though, as well as the burial date. You can then contact the cemetery with this information if you want to find his actual grave location.
