Based on the provided table, find the positions of cells with the subsequent values. Return their locations using the JSON format {'value': '<cell value>', 'location': (Row_ID, Column_ID)}, starting from 1 for both row and column IDs. If a cell does not exist in the table, denote its location as 'DOES NOT EXIST'.
The target cell values:
1. '1961';
2. '25';
3. 'Crossfield Successors, Arnside';

2. {'value': '25', 'location': (40, 1)}
3. {'value': 'Crossfield Successors, Arnside', 'location': 'DOES NOT EXIST'}
