Seconds Out is a go-to guide for the UK issues. I've found it very useful in ID'ing types for my collection. Unlike the WTI, it has pictures. When I saw the American section it inspired me to start doing my own books--i couldn't make it worse...
As for new stuff, these finally landed from So. America, so say hello to my little friends:
1956 Crack Gigantes de Figuritas Sport Marciano
1952 Figuritas Lali Archie Moore
Both rare as hell. I hadn't seen the Marciano offered for sale in years and the Moore was one I'd never seen before.
