Yet another new coupon has surfaced and it is a beauty dating to 1888. The new coupon, below, is the first I've seen that appears to be directed to a specific geographic area. As you can see, the coupon is directed to Goodwin's west coast agents, Mr. Mau, Sadler & Company, complete with a San Francisco address if you wish to order an album. The coupon is very similar to the more generic 1888 coupon, both advertising the two albums available in 1888 with a 75 certificate requirement. This coupon may have been packaged in a Gypsy Queen pack (popular on west coast) with either an N162 or, perhaps, an 1888 California League GQ.
Here are the four 1888 coupons known to me (Floral Album coupon does have an upside down back):
Here are the three 1889 coupons known to me:
I'm sure there are more to discover, would still like to find an 1888 example that mentions baseball cabinets.
