Any help would be greatly appreciated.

As you can see here; the first congress for the organization was held in April of 1891, from the 14th to the 17th.

The Whist marker is engraved with the date of April 27, 1891.

I am searching for any information as to what games or event connected to Whist or any other card game was held on that date.

Thank you,

John Benedict
