Well, wedding close to sea, I presume. The taped lower right-hand corner tells me this photo has seen a lot of love over the years. Very cute!
My grandmother and I were married on the same date. Since she passed away and could not attend, we had her picture at the altar.
My parents had my older half-sister in their wedding, she and mom had "mother-daughter" vows. My mother made her dress (it weighs fifteen lbs), my dad made his garb and my elder sister's.
