Oh yeah, I think I see what you mean from Google! They're also quite shiny and with a similar layout. Most of the ones I own that have some age just have this (I guess more easily mass produceable but less pretty) pattern

Well if you appreciate them, I have more to show off x3

That one is an 1844 edition of 'The Concept of Anxiety' by Søren Kierkegaard (writing as Vigilius Haufniensis). It is written in a (simple) Gothic (at least I think it is) typeface, too, since Denmark was still using the script at the time
