Identification Of Spanish Stamps

Can anyone on this forum please tell me the Scott catalog number of three Spanish stamps I have in the 50c, 1, and 4PTA denominations each showing the king and queen facing each other with the crown between them but over their heads and with the top heading reading "exp de industries de Madrid". On the left margin is "corrals" and on the right I assume is the date "ano 1907". The 50c is green, the 1P is red and the 4P looks to be brown violet.

I would think this should be easy to find but I have search all Scott catalog pages and still cannot locate it

After doing some research I have discovered that the 50c and 4PTA are both Scott #296a, I could not find the number for the 1P stamp.

papa, they are semi-postals so you'll find them toward the back of the Spanish listings.

EDIT: I take that back. I don't know where you'll find them. They are something like cinderellas apparently. Here is a note I found: "King Alfonso XIII & Queen Victoria Eugenia/Stamps only valid within the confines of the Exhibition, and required to be duplicated (by the organisers) with general issue stamps

Here's a bit more: http://www.stampcollectingblog.com/...-forgery.php

Here are your stamps from my collection.

Floor trader: if you were to put them in a Scott album, what year and what section of Spain would you mount them?

Scott lists them after 296, but I'll be anxious to hear what floor does with his.

Pardon the interjection. Coincidentally, a couple of weeks ago I put these very stamps in my collection between Scott 296 and 297.
