Two Argentinean combined postal entire uses from 1943

Both in the correspondence of retail outlets.

Two 1942 slogan covers to the US

 Both have the same old style slogan (slogans in this format were used in the 1930s): "Do not include currency in your correspondence - Use the postal money order service or the declared value service."

Two 1943 slogan covers to the US

Both are ship covers and have US tape censorship. The first slogan reads: "If you register your change of address your correspondence will not be delayed or returned."

This second slogan reads "The national telegraph acccepts out-of-country telegraphs."

Two 1943 covers to the US

 Different stamps were used to fulfill the same 1.15 pesos rate.

Two 1943 Continental Grain ship covers.

 Both are regular rates with transparent censor tape, which, as is the case for the first cover, the outer plastic sometimes falls off. The slogan on the first cover reads: "Send money out-of-country using the post office."

Two 1943 1 peso clay covers to the US

Both are censored.

Double-censored 1943 cover to England

 These are rare since we either find US censorhip or Englsih censorship on applicable covers, but not both on the same cover as is the case here. The 'Via New York' marking is rare, but I don't know if it is private or was applied by the airline.

A 1943 cover to the US with five 1 peso clay stamps

 A rare find with so many of these stamps. While the 1 peso clay is not rare, it is also not common. I consider it somewhere in between when it comes to rarity. They were used for a sustained period in 1943-45. 

Two 1943 covers to England

I hope you can tell which one is the 1 peso on clay paper from these two covers. I will give it away further down this post. The 20c commemorative on this first cover is on clay paper.

Yes, this one. This stamp is on clay paper.

Two more 1943 Continental Grain covers

I do not see any clay stamps in this selection except for the 5c stamps on both covers.
