Comic books/Missing Duck Data4 messages

What are we missing in the Donald Duck series (in the database that is, not in your collection)
- Comic Good (predecessor Donald Duck Extra)
- Donald Duck extra covers (various years)
- Various advertising publications
- Donald Duck Junior (magazine)
- Duck Out (magazine, football)
- A lot of 'one-shots'
Who has these expenses and can add them to the database? And who else has missing releases?

I have all the Stripgoeds and DD Extras, but they are nowhere near my turn.
Probably I will not start working on the magazines until after I have done my books.

I still have a pile of DD's advertising work and by the way, 2/3 of the advertising expenditure in general is not yet in CataWiki.
And at the rate that I can make time for it, about 10 items per day I still have years of work.
So a new hobby.

Or - as Willem Naber said - "So you do something else with your books!"
