Recently I registered on this awesome site as I started to organise my dad's (passed away some time ago) stamps
collection. Today I found a stamp with a weird colour error and I'd like some advice/expertise on that. It seems that
Red dye smeared while printing that colour took place.
I scanned the error along a good stamp aside, but the file is somehow large (>3 Mb) as I scanned at 2400 dpi so i scaled
it down. The right image is the same stamp with correct colours.
Forgery is out of question as the stamp was in an envelope with at least 8 copies of the series containing this stamp,
as my dad was ordering 2x2 +1 blocks on a regular basis. Very confident he didn't see this.
If someone can help me with an advice/oppinion/expertise i'd be much obliged
Thanks in advance.
