Somewhere in between the S&L bank crisis in the 1980’s and the more recent Subprime mortgage crisis the Pennsylvania State Bank decided to send a “thank you” to their loyal customers and offer to refinance with a home equity loan. Now, I know U.S. banking history is not too interesting, but their promotional material is of interest to me. When you open the tri-folded business letter a woman’s hand offers a handful of small bills. This is the first time that I have seen a small pop-up inserted into a business letter. After all these years, it’s exciting to see something new. I could not learn too much about this pop-up advertisement, but my guess is the letter was produced around 1993 based on the documentation. It seems Pennsylvania State Bank has come and gone and now PNC is at that address. Maybe too many of their loyal customers took them up on the home refinancing offer.
