The Old North Church has its own gift shop. I imagine they have a lot of traffic and, judging from the online gift shop items, not much in the way of a quality replica of this historic building.

If made, this would be a 'cross-over' piece that could attract the interest of several other affinity groups.

As already mentioned, those interested in the Revolutionary War and others in Historic Boston and still others in Historic Churches might be interested in this purchase.

The Old North Church foundation and perhaps the gift shop could have a substantial list of past visitors to which HL could market this piece.

The city of Boston alone has lots of opportunities for more replicas of history places and buildings including "Old Ironsides".

IMO Harbour Lights' success in this kind of off-shoot assures their long-term success for those of us who look to them to continue their lighthouse tradition. I'd say "go for it!" -- Just remember the lighthouse collectors, too!
