Problem

A postcard addressed to Miss Frederica Clark at Highland Park, New Jersey, carries nine lines of numbers on the address side. Sweeping underline-like marks provide grouping within and across those lines. The facing picture is a staged farewell scene with people and luggage, captioned Good Bye.

The design is Bamforth & Co. No. 6025, copyright 1910. The cancellation is too weak for an exact mailing date. No picture-side handwriting accompanies the message. The complete numeric field and address follow; what does the writer tell Frederica?
