482A Is This Genuine Or A Fraud?

I read that some of these 482a stamps had fake perfs. What do you think? Fight Tuberculosis with Red Cross Christmas seals is the logo cancel which I read is from 1919. Found this in my deceased dads stamp collection.

Your stamp is a type I, rather than a 1a. (Note the toga button and rope are weak on your stamp.)
Thus it is a genuine 409 or a 482 depending on presence or absence of a watermark, with Schermack type III vending perforations. And far more likely to be 482 due to the 1919 use, which I agree with, as you found out, this slogan was used only in December 1919, and almost exclusively in New York City. Here are a few full examples:

Great info, Thanks!
