Old CCCP Letters Name

Dear sirs

I need to know what is the exactly name of the attached lot .
Is that hologram or hilogram ?

Are they not aerogrammes?

Peter

I'm not sure what the question is. CCCP is an abbreviation in the Cyrillic alphabet for Union of Soviet Socialist Republics, or Soviet Union.

He asks what these are.

Three of them are going to Cairo (also marked 'Avia'). Top right is going to Kalinin, but the addressee has an Arabic name. Related?

Sorry but neither of these is an aerogramme - they are regular prepaid covers that were quite numerous in the USSR /Soviet Union.

The first one is for inland ground mail (the 4-kopeck postage rate), the other three are for inland airmail (the 6-kopeck postage rate). When used for sending a letter to abroad they needed uprating with additional stamps to 16 kopecks in total for Cairo.
Someone tore the additional stamps off these covers, and they are just a useless trash now

Thanks for those infos.
But did the USSR issue any aerograms ?

Franlkly speaking, I can't recall any, but I may be mistaken - I have never been interested specifically in aerograms, and they were not popular in the USSR (in case they existed).

I asked the question in a Russian forum, and they confirmed - there had never been an aerogram issued in the USSR.
All those offered at eBay and Delcamp as Russian / Soviet aerograms are prepaid covers for airmail.

Thank you.
