Hand-addressed and free-franked mailing panel, 5.5 x 3, addressed by Zachary Taylor to "Henry Grinnell Esq., New York City," and franked in the upper right as president, "Free, Z. Taylor." Retains the original red wax seal on the reverse. In fine condition. Taylor received franking privileges upon his ascent to the presidency, and passed away before his term ended. Given his short tenure in the White House, presidential autographs by Taylor are especially scarce. Encapsulated in a PSA/DNA authentication holder.
