That's an interesting Franklin, Ontario postmark. Not only is it a DPO from a now-ghost town but the imprint is unique, too, in that the month is overprinted "JU" (June) with "JY" (July) and the year (17) is also inverted.
To quote a passage from one of several ghost town websites:
Quote:
Around 1913 the CPR built a small flag station about halfway between Fleetwood and Franklin. Although the station was used primarily for shipping produce, it was both busy and profitable for many years. By contrast the railway line in Franklin was not a money maker. It was closed in 1928 after the GTR was taken over the by CN Rail. After the loss of the railway, Franklin was never able to recover.
