Pommern 1923 Airpost Stamp

Hi,
I am new to the community and happy to be here. I tried to upload a picture of a German stamp (Deutsches Reich 30) but was unable. I will keep trying to downsize the stamp. In the meantime, has anybody seen a stamp with a Pommern 1923 overprint with the old time single wing black airplane on it. I have them for sale on ebay under German Pommern so you could see better pictures there. Are these fake? Thanks

Cropping the picture/scan may help. Crop/cropping is my new buzz word I learned here recently.

JOHN -----Those airplane overprints on German Inflation era stamps are modern forgeries . If you want I can have a rubber stamp made with that design [like the Danzig early airmails ] . Plus I got about 400-500 of those stamps . So I can get the rubber stamp for about $25.00 custom made and stamp those 400 stamps with that overprint . I'll sell them to you for 20 cent each and you pay me $1.60 per sale and you can continue to sell them at $1,000.00 per set That is $1.60 for me and $998.40 for you .....p.s. I FEEL I would be ripping you off at 20 cents each.

Here is something I purchased recently at about 10 cents each . This is what I collect FORGERIES and FAKES .
