Hobby is probably not the best description for this web site. It seems to be entirely a web store selling some kind of history related documents (or books, I am not sure).
Assuming I was not deceptively directed here and interested in what was being sold, the links all have the same picture even though each title/author is different. This is confusing. Actually, it's kind of weird, and makes one think maybe this is not a legitimate web site.
(If we're just seeing a prototype and you already intend to have a unique picture for each doc then never mind.)
And for the documents I clicked on, there was just author and title, no info, no synopsis, no preview. There is a "Reviews" link over on the left but it's apparently waiting to be populated by future customers so it's no help. Aficionados of these historical eras are probably like everyone else, and will be put off from buying without some more idea of what they might be getting.
Last, the popup to ask about currency conversion looks like those annoying ad popups some web sites run that have to be closed. This one doesn't have a way to close it. It does no harm and can just be ignored but that's not obvious from looking. I'd suggest another method. Many web sites just have several national flags that one clicks on to convert the language and currency. That might be a better user interface if available.
Sorry for the mostly negative response. I think it's smart you are checking what people think before going live.
