Vtg Grieger's Bonus Stamp Book & Miner Stamps 1956? Mineral Shop Pasadena CA

Description

A really nice old stamp book that's almost pristine. Like I said above the back cover has a few wrinkles, but is not torn and I actually didn't notice them at first. These are bonus saver stamps for the Grieger's Mineral Shop, 1633 E. Walnut St., in Pasadena, California. At one time, it was the largest mineral/lapidary mail order in the U.S. Yes I searched for it. I'm estimating the date as 1956 since they were at the above address then.
It has cool graphics on each page and all are different. There are no stamps in the book and 90 stamps on the full sheet, plus 5 loose ones which are bent. It's a little book with 15 pages (30 front & back) not including the covers.
5 7/8" by 3 1/2".
I will put thick cardboard around this so USPS will hopefully not bend it.
Please ask questions for more information or pictures.
Thanks!
