Hi. My dad sometimes collected First day of issue stamps and sent them to us, his children. While searching through a pile of these I came across these 2 covers. One is clearly the wrong date- I have a cover from the same post office with the correct date too. And another FDC has me baffled entirely. Any ideas how unusual these are?
Thank you in advance for any info.
this with the wrong date
This with the correct date
And what is this?
