Hal LewisAccording to the ads in my Beadle Dime Guides...
the 1867 versions say "Andrew Peck & Co., 105 Nassau"
while the 1868 versions list:
"Peck & Snyder, 105 Nassau"
This is consistent with the NYC directories from that time as well.
Peck & Snyder obviously merged with each other at some point in 1868... probably early in the year before baseball season when the dime guides came out.
