Heligoland Cinderellas

While browsing for legitimate 1935 Silver Jubilee stamps, I came across these "Heligoland" cinderellas on eBay:

There appear to be 1946 Peace and Victory, and 1953 Coronation varieties also. Does anyone know who produced these? Are they contemporaneous, or modern?

 

It use to be part of Germany but was taken by Great Britain in the second world war, Britain released them to be proud of there war prize.I have a small book of stamps. title. Peace and victory issues of the British Empire 1945-1947 A footnote to World War Two 1940-45 Scott Publications. I should add that set to the book. All stamps in my book are not used and not hinged, It even includes Canada, Just one stamp A ten cent Special Delivery.

 

Thanks everyone. I assumed they were cinderellas, and judging by the appearance, new rather than contemporaneous. Not considering them for my 1935 Silver Jubilee collection, but just curious.

 

A good reason to re-edit a former post:
Germany received the rock-island of Heligoland from Britain,in
exchange for Zanzibar and Pembar,formerly islands belonging
to German-East-Afrika.
Seemed to to be a bad deal for Germany,to give those two
valuable islands in the Indean Ocean and receive in return Heligoland,
a rock with no more than some 2307 often unwillingly german inhabitants,located in the German Bay.But strategicly Heligoland
was an "unsinkable warship",shielding the german coastline.
During WW I civilians were evacuated from the island and it was
used as a military fortress.
In WW II the military installations had been enforced,but due
to the progress in modern warfare,the island was rather sidelined.
However shortly before the end of the war,the R.A.F. attacked
Heligoland on April 18th and 19th,1945 with about 1000 bombers,
dropping more than 7000 bombs onto the island.All houses were
destroyed,285 people were killed (amongst them 12 civilians).
But the majority had survived unharmed in the vast bunker system.
After the war ,the British tried to destroy the military installations
on the de-populated Heligoland (all civilians were evacuated by
Germany after the April-bombing-raid) and hopefully the complete
island by the,at the time,biggest ever convential explosion.
Although badly damaged Heligoland withstood.From then on
Heligoland was used by the British as a training target for bombers.
After the german parliament had asked the British unanimously
to give the island back (even the GDR did join in),Britain agreed
and gave Heligoland free.The population was allowed to go back
in 1952.
Today live around 1300 people on Heligoland,making theirs
livelyhood mainly by (duty-and tax-free) tourism.
In the last years Heligoland has become a service- and
administration-centre,for wind-parks (electricity generation)
in the North-Sea.
Stamps,I can think of,featuring Heligoland:
Heligoland,50 years part of Germany,issued Aug.9th,1940

Heligoland liberated (from british occupation),issued Sept.6th,1952


Tourism-series,issued Oct.20th,1972 (50 years after liberation from
british occuation)


Defintive,issued June 21st,1990 (100 years part of Germany)
A near idential stamp,what I do not own,was issued for (West-) Berlin.

I do not have any stamps of Heligoland under british rule (1807-1890),what were issued between 1867 and 1889.
They are a minefield of forgeries.
