Derek,
I, too, received this same email today from Cecilia, who comes across to me as a very nice person. I've had several communications with her over the past several weeks re her 1924 Diaz cards. In my first communication, I asked her if she had any Washington Senators cards, hoping that I might be able to pick up some of the ones I need for my card collection of players who were on the Senators 1924 World Series Championship Team. She kindly gave me a list of the Senators cards she had and promised to list all of them on eBay at the same time in the near future. She did as promised, and I was able to win 2 of the 3 cards I badly wanted - "Oyster Joe" Martina & W.H. McGrew - which arrived in today's mail.
Despite placing an insanely-high, last-second bid, I was outbid on this this poor-condition Paul Zahniser card:

I assumed that a 1924 Diaz set collector decided he just had to win this card, regardless of the cost. But, Cecilia kindly informed me that the Zahniser card was won by a Zahniser relative with the same last name, which softens my disappointment a bit!
