Such was my dear wife's (RIP) love of this catechism, and the loss of it in modern times, that she had 1000 printed to be sold to cover her expenses. Requests came from all over Ireland for this catechism from parents and grandparents for their children that all 1000 were gone just after she died. I decided to continue her apostolate and got another 1000 printed. I now get requests from people who remember it in their youth, a catechism that makes armature theologians out of readers by way of Q&A.
