Thank you, sir. You've made my day. It is a rare opportunity to encounter someone who might know some things about Stahl-Meyers, cards and the frankfurters themselves.
Some questions I had were:
How much was a Stahl-Meyer Frankfurter at the Polo Grounds?
Were they any good? What was their reputation?
Compared to other hot dogs sold at the Polo Grounds, how did Stahl-Meyer rate?
What grocery stores carried the Stahl-Meyer Frankfurters?
Were they expensive, as compared with other brands such as Armour or Hygrades? How expensive?
Did you personally collect the Stahl-Meyer baseball cards?
Do you recall any friends and acquaintances who collected them?
How did one find out about the Stahl-Meyer baseball card promotion?
Were there any TV commercials or newspaper ads that you remember?
The sets were small; nine cards in 53, 12 in 54 & 55. Were all the cards issued at once, or was a different player for each team issued periodically?
Here's a good one. Do you remember what you and your chums used to do with the Stahl-Meyer cards you got?
Well, at least this isn't 20 questions, though I'm just getting warmed up. Since the subject could be considered a little daunting (well, what does he want to know????????????) Just thought I'd chime in with a few savory questions on the matter. Thanks most awfully again.
