David, is there supposed to be a pic attached, or are you just asking about Beatleworld and Caiazzo? if its the latter, they are highly respectable with regards to Beatle items.
If Frank Caiazzo says it's good -- It's good. No need to look any further and have people try to talk you out of it who don't have Frank's knowledge. Also any auction house worth it's salt will take it with Frank's COA.
