Vern, I am aware of all that. But if you look closely, that is a modern view of the Alamo with current landscaping. It is the only needlepoint kit my wife could find, and it took her several weeks to complete.
The original 1824 Mexican Constitution flag that was captured by Santa Anna on March 6, 1836 is (or was) on display in Mexico City under deteriorating conditions.
The current Lone Star Flag is what is flying on the Alamo now - last I saw it was 2 months ago.
