1899 Netherland Stamp-02 C.-Brown Figure-Imperforate Variety???

Hello forum...!

Trying to figure this stamp out, is it a postal envelope stamp?

Or is this an 1899 Netherland Stamp-02 C.-Brown Figure-Imperforate variety?

The 01 C. red (1899 - Imperf. - NVPH #51va, Sc. #56b) and 2 ½ (1899 - Imperf. - NVPH #55va, Sc. #60b) - Green both have listed imperforate varietes but I don't see this one.

Any info...? Thanks!

Cut from a envelope , called postal stationary

Floortrader is right,a cut out from stationery

From the catalogue: a picture of a 1,5 cent example complete and a partial 2 cent example. Kind regards, Johan.

Observing the part postmark on the left hand side, one could imagine a missing stamp, suggesting the postcard lettercard was "uprated"

Heya floortrader and rod, thanks for the help as always. I get confused sometimes as to what is "technically" postal stationary compared to an imperforate or essay type?! Good info. about the "uprated" postmarks as well reading about it now :)

Cheers Johan for that great reference scan and taking the time to find that! Nice to see those "BRIEFKAART" full envelopes would love to find them someday...

If it were an imperforate error it would have come from a sheet of them. The sheets have the stamps fairly close together, which means you wouldn't be able to have the wide margins at the side without seeing portions of the design on an adjacent stamp. An essay or proof would be a single design with potentially large margins, but they wouldn't have been used so wouldn't be canceled. If the paper is thick card stock then it likely is from the postcards illustrated above. If on thin paper it would be postal stationery instead.
