Since I specifically asked for this section I might as well post with two of my lingering questions...
My NSFGE friends who have already read my impassioned plea can ignore this - I am hoping the influx of different collectors and experience can help!
Looking for any sales results or any knowledge of potential value for these two posters:
1) It! Terror From Beyond Space - 1958 - UK Quad
2) 20 Million Miles to Earth - 1957 - Australian One Sheet
Any help is very much appreciated!
