For some reason the first Massey Shirts thread #1 lost it's reply buttons so I will continue with thread #2.
Here is a nice looking shirt I picked up at our local Fleet Farm years ago.

Here is a nice looking shirt from the Twin Power Club of Canada. I believe this was also a Steve & Sandy design.

Here is a shirt with the usual looking logo with a different twist in colors. This is one I got from the Iowa show and is a Tina Van't Sant design. I believe you can still get one from here if you want one.

Here is a nice looking Wallis design with the Cub Jr on it. I think I got this one from etsy or ebay.

Although this doesn't probably qualify as a Massey shirt we were there representing the Massey snowmobiles. 4 years ago today this show took place at Mac's. This is a campground just 1000 feet from the Power Dam just north of Rochester and south of Mazeppa. Not much for snow that year but plenty of alcohol and good food. Great place to go for a beer or burger if your ever in the area. One of the biggest promoters of this show passed away 2 weeks ago so it should be interesting to see if it will keep going.

They are still available.

Here is s shirt design from a show at the Little Log House show grounds near Hastings, MN. This was from back in 2004 when they featured Massey. This is a bit different style shirt as it is a sleeveless shirt like a tank top style. I believe the reason they went with this style shirt is that every year they have this show it is like 105 degreese there in the shade.. This shirt is not one of my most favorite shirts. The imprint on the front is like wearing a rain coat as it is like rubber. A good shirt to wear if your going to be eating and spill on your self as you can just wipe it off because it won't soak into the shirt. You may recognize some of the people or tractors in the pictures.

38 degrees out today and pouring rain in the middle of January in Minnesota, this is just unheard of. Usually this time of year it is 50 degrees below zero and windy. Here is a Wallis shirt design I got off etsy. Looks alot better in the picture but is so blurry when looking at it in person it makes you feel like you are drunk. I have this shirt in both blue and black.

Here is a nice looking shirt with the 6 tractor line up. I believe this was also a Steve & Sandy design. Great looking shirt for any occation.

Another Steve & Sandy design is this wild looking shirt with a pony jumping out of the grill. This shirt was inspired by Steve's love for anything to do with the Pony tractors. Steve is the Pony king, I believe he has 31 different variations of the Pony tractors in his collection.
