First, I apologize for the three posts which probably went under US postcards. Still learning how to navigate this site--doesn't seem hard but sometimes DUHHH. Patience please.
Can't find this!
Hand cancelled, March 25, Paid 3--on a one penny demand stamp?, and initials. Seems to be lilac or pale/light lilac. Anchor watermark on back. Jumbo stamp and perf gauge doesn't go small enough.
Any help on ID or value would be really appreciated. Novice here.
