Thank you for the info.

小弟正在尋找那時的三分錢是長什麼樣子的. 要不然就是湊整數一次買十張. 小弟之前提及的美國PNC票就有5.3分, 無法只買一張.

Thank you. I'll check that out.

還在尋找噴射飛機的自然片.

這一封銷 1889年二月二日 Danielsonville Connecticut.貼SC#213 2 分Washington像. 設計信封的人從事印刷業, 以綠色背景加上一枚綠色郵票看起來郵票變大了.

尼克森當年37歲以眾議院議員身份競選參議員. 片上寫道

"Here's a man you can depend on!"...................昏倒.

這封可蓋(郵聯)戳? 非實寄大概是要求概的吧.

小弟最愛的飛雁封. 這是他當第一任副總統時吧! What's inside? Newspaper or Magazine?

早期從國外寄到台灣加貼台灣郵票 forwading是否也很常見? 美國現在是使用Postal Automation Redirection System (PARS).

It  is designed to identify “Undeliverable as Addressed” (UAA) letter mail at the first machine handling and automatically redirect it to the correct destination.

美國UAW (United Automobile Workers) 影響力之大恐非常人可想像.  為了要配合打獵季節,  他們與三大汽車公司的四年合約裡有一項是將退伍軍人節從星期一移到星期五................所以明天放假.
Just found this cover in a box. The cover was franked with a SC#65 and was sent in 1866, which is one year after the civil war.  It has vertical imperforation on the left side.

Good point. I've thought about that too.  If it was mis-perforated, let's say the perforation  was somewhere on the further left which is outside of the stamp, what I don't understand is why the left side has a vertical straight cut (it almost looks like done by a machine)? Or someone must have used a pair of scissors to get that done. The cover was among a pile of very cheap covers I purchased a while ago and I'm not sure why someone would try to fake it without gaining anything, but that's not important since the cover doesn't mean much to me. It is the stamp itself that I'm interested in.

I checked the Scott catalog, it does say that there are vertical pair w/ horizontal imperf existing but does not say anything about vertical imperf. I guess your suggestion is probably right.
