Imperforate Stamp Identifiation

Hi, I'm sorry if I'm not posting this in the right place.
I have inherited a lot of stamps and some of them caught my eye. I have found absolutely nothing on the internet and I have many of these. The first one seems to be Swiss, the second British and the third Japanese. Can anyone tell me more precisely what they are? Thank you !

The British stamp is a cut-out from postal stationery - a newspaper wrapper if I remember correctly.

I'll look into it, thanks a lot!

They all appear to be cutouts from postal stationery items, i.e., postal cards, letter sheets, or postal envelopes.

The first one is from Switzerland indeed

As posted, Switzerland, GB and Japan.
Unsure if your GB has ink on Her Majesty's visage, but she looks decidedly grumpy.

I'll check your GB for catalogue number

Easy catalogue Brightmore Cat#7 (1883) Newspaper Wrapper, ½d halfpenny Green, white paper, hair ribbon shading is horizontal.

Still checking Huggins Baker, their catalogue is like learning a new language.

Thank you for all your answers and clarifications, I will be able to see this more precisely!
