Erroneous cover and author on the book "Manual de vexilología: Nociones y términos propios de la ciencia de las banderas"

[Gortius]

The cover of the book and the registered author are completely wrong.

Here: https://www.edicioneshidalguia.es/?pr..., in the publisher's website can be seen that the cover is a completely different one: white with some flags in the background and that in fact the author is NOT Adolpho Arrietta, but "Vicente Cadenas y Vicent".

For some unknown reason, other websites also label Adolpho Arrietta's "Works" as Vicente Cadena's "Manual de vexilología", when these are two completely different books.
