Ken McMillanDid a little further research on my w575-1 and it turns out that this is probably a Koester's bread card. R.M. Hayes & Bros company is from Hagerstown Md and E.H. Koester bakery is from Baltimore Md. The two cities are approximately 70 miles apart making the card very likely to be a Koester. The two card types are virtually impossible to tell apart and geography makes this probable.
