I’ve had the very great pleasure to work with Alchemical Press and its owner Paul Hoeffer on the layout of a number of their products.
In particular, the Mice of Legend line which includes the Perils of Portal Lake campaign setting and adventures, in both OSRIC/1E/OSR and Shadowdark variants. Over on DriveThruRPG they also have OSE & 5E conversion guides. From the Alchemical Press website…
