Mack’s Mountain Club had a couple of orders in 1947 and 1948. Their original order in 1947 had a weird order.
All same SM font...same card
50c. Red
1.00 orange
1.00 Yellow
5.00 pink
5.00 brown
10.00 Lavender
They must of had a 2nd operation (2 colors of same denominations)

Then they order different colors...
5.00 green
50c Blue
A few months later.

Different names on cards ....but alternating. Sam 3 times...C.R.ordered once in the middle.
