Wow, I did a check and was a bit shocked. Life in 1948, available everywhere for 35 cents. Inflation adjusted to $3.45 in 2013
Aperture, well good luck finding it. But you can subscribe for $75, I think that is 4 issues, that is about $19 an issue (with worlds better production values than Life magazine I would assume), some really good photography too with a bit of the artsy fartsy stuff on display also. (Just because no one understands you does not mean you are an artist)
For what it is worth my exposure to good photography started in the 50's as a young hick kid growing up in southern Indiana. My great aunt Willa, a very imperious and refined lady, was concerned her 7 year old nephew was not having his horizions expanded enough so she got the family a subscription to The National Geographic. I spent many happy hours with that magazine and the often included maps.
