4 Zeppelin posters

[IA85]

Hi,

I picked these up recently and was wondering if anyone can tell me anything about them. I believe they are originals, but am not 100% sure.

I have looked into the knebworth poster and at 17"x24"(approximately) the size seems to fit.

I have been unable to find the budokan poster in the same size, all the ones I see online are much smaller and all appear to be repros.

The other 2 I am not sure about. I assume they are not concert posters, but am thinking they may be promos poster, and not store bought.

This is very similar and maybe mine is just faded at the top?

If anyone has any info on them, it would be greatly appreciated. I have looked all over the internet, but haven't been able to locate identicals matches except for the Knebworth poster.

Thanks

Kyle

PS sorry for the poor pics, I didn't realize they were blurry. I can get some better pictures if neccesary.
