Every picture I have seen at him at Beth Shirim and other private places are with a bottle of alcohol.
How many pictures have you seen like this?
I know there are a lot of reports of Rutherford's heavy drinking and bad character. Jim Penton's book goes into this I seem to remember, and there is the Olin Moyles court transcript which reinforces this impression. There are enough sources of information for me to be convinced. But I don't think i have seen pictures of Rutherford with an alcohol bottle, besides the one posted. There is a youtube video with him gurning a bit at Bethsarim but there no bottle.
Are you sure you haven't misremembered the photos because they fitted the image you had about him?
