Hm, I just had a look at my MIB (read: Mint in bag
) DS-sets. A genuine DS-bag with the logo printed on it leaves a margin (about 2cm wide) where there's no printing all around the bag.
The bag in pic 1 doesn't look like it has that margin, it looks like cut from one of the DS-bags.
It IS a fake, I think.
By the way, DS service started working with four-digit numbers AND catalogues in 1984. As far as I know, all sets ever shown in these catalogues are listed on playmodb. Could it be that this set has escaped collectors' attention ever since AND never been shown in a catalogue?
