I've been collecting for over 20 years and have never used PSA. JSA or BAS. I have learned to trust myself. No single entity can authenticate everything with the same degree of accuracy. That is why I specialize in just 2 - Jackie Gleason and David Bowie (1976-1980). Normally I do copious research before a purchase but as I said, this popped up. I showed to a very knowledable friend so OK there but it was said to be hampered by the dedication and inscription - neither of which bother me.
