So what you are saying, is that you have spotted something familiar to you. That is not going to be consistant with the rest of us. It may not be within our sphere of knowledge.
When I bid on early album pages of Turkey, it is "fly by your pants" as you never know, till items come under the magnifier. I'd say I get about 50/50 return.
I sometimes note, Turkish stamps are hinged willy nilly to fill a stamp page, which makes it look exciting. The incorrectly placed stamps have newer hinges, so you cotton on a dealer or seller, is "enhancing" lots.
This is an interesting lot. Granted, one takes a chance by spending $400+. But I think I would have done it.
Couple people mentioned the Black Ball ferry cover on picture #8. I rode the ferry from Port Angeles over to Victoria and back in June, 1982. It's an interesting way to get mail into the US post system.
In the 9th picture, I note a couple covers to B. Schulze in Port Angeles. He was a stamp dealer at the time, but I don't know if he is still in business or even living. The 10th picture seems to show some early Luxembourg sheetlets that may have some value. I also like the old, non-US, cut squares. There is some damaged stuff, as floortrader mentioned. But I've bought old stockbooks and binders of this stuff in the past and generally liked what I got.
