They are newsprint periodicals, weekly issues, only average eight pages, about 8 7/8" x 12 1/4". They are better than typically expected condition being not badly aged of the paper, nor having much wear at all for most issues and not a single bad one. I did not turn every page of every issue but I expect they are complete. They have been loosely rolled up and they are very awkward to handle at this moment, however, as they were only rolled loosely and not folded it didn't leave any creases, they just want to curl up some. So you won't have to leave them there forever but you should put them under something heavy for a bit of time to get them to lay flat. Putting them into individual bags would make that a lot easier. Actually I just did one and it does. I don't think they have been rolled up for 70 years, maybe not even 20, I expect they will re-flatten. Follow along please, the publishers originally had a title "Current Science" and there are not any of those included. In WWII they started a companion journal "Current Aviation" which went a few years but for whatever reason they merged the two. The first such merged issue is included and you can read the notice at the bottom in one of the photos here. The lot includes 15 copies of the Current Aviation, and 18 copies of the merged Current Science Aviation, making 33 issues all together. The merged issues have an "Aviation Section" but the only thing is they are still the same net average length for the entire issue, so you are getting less aircraft coverage in the merged version. But you are getting very scarce content. You have probably never seen an issue at all for sale much less a run of them, so that makes this a scarce opportunity as well.
