All the ones with captions on the front are likely Type 3 wire photos (photos printed off of a duplicate negative within roughly two years of the photo being shot). If they are not Type 3's they are type 4's (same thing but printed after roughly two years from the photo being shot). It's difficult to tell what era the photo paper is from online unless it is in the caption or there is a date/publisher stamp on the back.
