The free flags were handy if you knew the general date and size of your expected ship. But of course the paid custom flag service was more accurate. https://t.co/BEBq1WoH3Q — PolitiTweet.org

Think Candy Crush invented freemium? Think again! In the early 19th century the Portland Observatory hoisted flags to spot incoming ships. For free it noted basic qualities like "brig" or "sloop." For an annual $5 subscription fee merchants got their own flag. https://t.co/WB8TuzB7bD — PolitiTweet.org

The many barrier islands around Portland make it difficult on the wharves to see ships until they're almost in the harbor. Using its powerful Dollond telescope the Observatory could see 30 miles out, allowing merchants to ready dockhands and reduce turnover time. https://t.co/Uu5ea5DsWI — PolitiTweet.org
