Catalina post card, that's where I live and my girl friends grandfather used to take covered wagons to the other side of the island before cars and the Wrigleys were on the island. My guess as values could be $5 to $25 depending on content. I don't think postmarks or cancellations or writing deters value to much, but unused and in good condition would most likely bring the higher value and price. Would defintely like to see more especially any of Catalina, Long Beach,California,Tahoe,Reno, Las Vegas or maybe you just want to sell them all ? email me if you have an idea a single or whole lot price. tormor33@icloud.com
