I have purchased from them before, but only after confirming authenticity on here. I used them to submit items to PSA. I have no complaints about their service, but some believe that third party authenticators are more lenient on their items due to the volume of items they submit.
Post the autograph you like here and I'm sure many people would be willing to help.
Same question came in last days and here's my response regarding the big number of Beatles autographs (sets and solo) offered by PeePeeCee and friends:
When The Beatles were on tour in the 60's in US they had no time for music and crying fans because all four had to write autographs (day and night) for all the wellknown dealers in US from west- to eastcoast. It was easier for the Beatles and four lookalike guys imported from Mexico are playing at the concerts. Remember the words of Lennon "I've got blisters at my fingers" because of writing autographs not playing guitar.
