Hans And Alexander Fraenkel, E-L Stamp Co. & Ayal Albums, 200 W. Broadway, C. 1964

I've made progress since my previous request but I still seek any and all info on my boyhood stamp dealer in NYC, Hans Fraenkel of E-L Stamp Co. at 200 W. Broadway. Who was this kindly man, and what was his relation to Alexander, publisher of Ayal topical albums? And to the great Berlin collector, Judge Heinrich Fraenkel of Berlin (d. 1907)? Any personal recollections would be most welcome, as they might help to spur my own weak memory.

Please advise this newbie if this post belongs in a different forum.
