I saw recently where a few members were reviving some old topics.
Who else as a stamp that was issued on their birthday (month and day) or a cover postmarked on their birthday (month, day, & year)? I'm going to get out my catalog and see what I can find for myself.
Well I found these US issues for my date of birth: 622, 1040, 1044Ac, 1086, 1144, 1734, 2611-15, 4121, C63a, C87, U642, U643
I also looked up issues for my wife & sons birthdays and our wedding anniversary.
