I recently acquired a group of the booklets scanned below (39 in all). Are these relatively easy to find? How many total series did they make? In searching the web I found some for sale on Spanish webpages for as high as 22 Euros but that appeared to be for a version that was published in 1939. Any idea on an accurate price for one of these (beyond what I paid myslef)? How were these distributed? Any additional information regarding these would be greatly appreciated. I am sorry for the OTish post but I figured these were close to NS cards as they appeared to be issued in series format. I can provide scans of the rest of them later this week if folks are interested in seeing more of them.
Thanks in advance,
