I recently took a trip to Baton Rouge, LA for work and came across this flag in my travels. This is the only German flag I have owned and from what I can tell it is a good flag.

It has solid reinforement tabs on the corners, along with 6 stitch lines on the long side of the flag and 7 stitch lines along the short end of the flag. The flag has very light markings, but is not marked 60×90 from what I can tell. I did read that any flag marked 60×90 is a reproduction and should be left alone. In my research I also found that these flags were only made in 3×5 ratios, is this correct?

The construction of the flag is cotton and does not appear to have been made on a modern machine. It has a very similar feel to all of my cotton US flags from that era.

The only marking I can make out is (Holland) and I believe this is an 80cm x 135cm.

Im hoping I made a good decision in the purchase, if not I guess I will have to chop this up to a (expensive) learning curve.
