Above, the kitchen in '06. This, as "readahs" will know, is a new bit of the house, constructed in the mid-90s. In John's time, there was an odd internal yard in this position, next to the garage overlooking the pool. An almost identical shot has been on here before - but, crucially, that one didn't show the external door. This one does, to the left of the pic...and if that's not the old Lennon-era front door, then it's Dylan caps for dinner tonight:

The current front door is substantially bigger than this one. After (or before) installing it, they must have decided to keep the old front door as well, but transplant it to the new kitchen block. And there it is!
So much of this blog charts the destruction of locale, that it's pleasing to report an unexpected incidence of endurance.
Knockers or no knockers.
