As to the bag:
The '2/62' might be the date of manufacture, i.e.Feb, 1962.
The prominent and colourful DDR symbol is unusual - I saw alot of DDR stuff at surplus wholesalers in the 1990s and most had the eagle, but few had the full hammer and sickle.
It's worth more as a very strurdy and usefull bag than as a collectable at present, but there may be a market for DDR stuff one day- a heck of a lot has been destroyed.
The cary strap is from something else- non DDR.
Otherwise, welcome to the forum...... it's usually very friendly and quite funny (easliy the best atmosphere I've come across online), so I'm sorry if your first experience of this forum isn't perfect.
