Vito did have a mustache in GF1.
The object Sonny is holding appears to be a garbage can lid,a reference to the one he beat Carlo with.
You are correct I am slippin'!
I remember, they were debating whether the young Vito, Robert De Niro should have a mustache or not and I got them mixed up
Thank you Lou Obviously it can only be the garbage can lid Duh!
