Superstition connection from nearly 40 years ago

We have old Adams/Ingham/Otto postcards tucked into different corners of the house here in Florence, Arizona, but it was still a surprise when Joan came across this coincidental family postcard the other day while writing and mailing out her own delightfully decorated cards and postcards to various parts of the globe.

In March 1982, my grandmother, Helen Chandler Adams Ingham (1919-2003), received this postcard at her house in Wallingford, Pennsylvania. It shows the Superstition Mountains, which I can see to our north if I walk a few blocks to the edge of the development. And it was postmarked in scenic Sedona, Arizona, which we visited back in early July (see a couple of pics below).

I'm not sure who the WTL's are, but they seemed to enjoy this part of Arizona back in the day. In March 1982, I was living in Montoursville, Pennsylvania, and surely had no notion I'd find myself living in The Copper State some day.
