Does anyone know of a company that will make custom slate/glass calls with a personal photo behind the glass?

In fact I do. Go to http://www.enticerturkeycalls.com/calls.html and scroll down to "Custom Personal Turkey Call". I don't have the custom personal call but I do have the "Wet-One Double Glass" and its a fantastic call. I've tried most of their other calls at an outdoor expo a few months ago and they all sound great, so i'm sure the personal one will too.

Jeff Wade from www.roostemcalls.com has made several for me. I give them to friends and family as gifts. Give Jeff a holler and tell him that Ray & Tyler sent you.

Gary Joffrion at Magnolia Game Calls will not only put the picture you want behind glass, the call will be one that you'll want to use every chance you get. His site is http://www.magnoliacalls.com

Just a side note; instead of scratching the glass up when you get it, try some RainChalk. You can apply it, sue the call, then wipe it clean and put it back on the shelf when you're done and still not have a scratch on it. It is available at Midwest Turkey Supplies.

I make them also. You can choose from over 20 different kinds of wood. Or if I dont have the wood you are looking for I will get.

Ever think about making your own? I haven't done it yet but I'm going to give it a try myself. Check these sites out.

You can get lots of info about call making at the NWTF website, there are a bunch of call makers on there that'll answer any questions you have.
