I spent a number of years collecting vintage fabric and feel I have a pretty good ideas on dating. Historically, I've considered those little medallion prints as being earlier but I recently found this piece that actually had selvedge information! The company name used was founded in 1952.
Scale is often a good way of telling things, the 30s prints tended to be smaller than the same basic designs used in the 50s for example.
edit -- that's a quarter in the picture for reference.
edit 2 -- the size and scatter of the polka dots looks more 60s to me than earlier, but it is so hard to date dots! I'm thinking the green is a pretty modern dye though.
