Old postcards can be like a time-warp. This one is dated September 25, 1902. According to the caption the lady in the tight corset is Isabel Bru. I assume she must have been a fairly popular Spanish actress once.
It seems that back those days postcards weren't intended for carrying written messages. The entire back side of this one is dedicated to the address. On some other postcards I found indications that it cost more in postage if there was writing on the back, other than the address, but not the front. Whatever the reason, I have multiple postcards where the writing is on the front.
